Main differences between ferrules and end caps

Main differences between ferrules and end caps

Ferrules and end caps are elements involved in the assembly and operation of a wide variety of products. They are usually quite small components. And, in both cases, they are responsible for playing a fundamental role. As they often make a decisive contribution to improving the end-user experience for a range of items.

This is the reason why manufacturers of very different products take them into account to complete their creations. From furniture makers to industrial piping manufacturers, among others, they know first-hand the benefits of ferrules and end caps. Now it’s down to you.

Ferrules and end caps

Whatever your situation may be, finding the part that best suits your needs means getting to know it better. Ultimately… in order to complete a puzzle you have to look at each part separately and take a good look at all its features, before deciding where it fits best.

To begin with, it’s worth pointing out that we are talking about two products with great similarities. For example, in terms of the materials used for their manufacture, or with regard to some of their uses. But, at the same time, they exhibit very important differences that make them distinct.

At FORTAPS we can help you with the first steps in finding the piece that suits you. Why don’t we kick off by getting to grips with what we are talking about?


Ferrules are protectors that are fitted to the legs of various types of furniture. And they are specifically linked to the contact that this furniture establishes with the floor. These elements play different roles directly related to the use of the furniture they complement. Thus they serve to avoid noises that would otherwise come from dragging the furniture on the floor surface, as well as the marks that these movements can cause. In addition, they are also designed with aesthetic and hygienic purposes in mind. First of all, they soften the finish of the structure to which they are attached. Secondly, they prevent the entry of dirt inside the tube.

End caps

End caps, like ferrules, are also protective. They are manufactured in different types of materials, as are ferrules. Specifically,  polyethylene is one of the most outstanding for its versatility and resistance. But there are also end caps made of ABS material or thermoplastic rubber.

In these two points the similarities between the two types of component are highly significant and striking. But the truth is that the differences that separate them have a specific weight. Since they are what precisely differentiate these protectors.

What is the difference between ferrules and end caps?

In a simplified way, it can be said that the differences between ferrules and end caps lie basically in their uses. We have already noted the functionalities of ferrules in the preceding text. Thus we mentioned their safety, hygienic and aesthetic properties. These roles are shared by end caps.  But, just as their functions unite them, they also differentiate them.

Differentiating characteristics

However, a note should be made here: end caps do not necessarily have to be fitted to a tubular structure (legs, crutches or canes, etc.). Nor do they perform their functions simply by complementing certain types of furniture.

On the contrary, end caps fit a wide variety of frames, devices, etc. The safety function is paramount in this case. Thus, they can be found as the terminations of some structures to avoid damage when any contact is made with them. But they also cover nuts, bolts and other parts in the frame of a larger structure. At the same time, they are designed to prevent dirt from entering the interior of the places they protect. As well as enhancing the attractiveness of the structures. As their name suggests, they cover protrusions, borders, fixing devices, etc.

As for ferrules, these are used to prevent slippages that may occur during the use of furniture, such as chairs or stools, for example. At the same time, they eliminate the marks caused by furniture dragging on the surfaces on which they are placed. And it is precisely on these fundamental functions that we must also focus when looking for the differences with end caps. The latter do not fulfill these two tasks.

Size as a differentiating element

Finally, it should be noted that, mainly due to the roles for which these parts are designed, ferrules are longer. To understand this, suffice to say that it is impossible for them to prevent slipping if their grip on the legs is not optimal. So, whether they are inner or outer components, they must ascend into their tubes. Whereas end caps need only be designed to cover a specific surface.

Benefits of external end caps for metal structures

Benefits of external end caps for metal structures

External plastic end caps are highly versatile parts, and their installation is essential to a variety of metallic structures. Indeed their role in the assembly of some metal frames is responsible for maximizing their usefulness.

This is the main reason why both manufacturers and specialists in the assembly of metal structures are well aware of the need for these elements. But it never hurts to put such important functionalities under even closer scrutiny. How about conducting a piece-by-piece examination of the relationship between external plastic end caps and metal structures?

What metal structures are we talking about?

Starting from the beginning, let’s first talk about the hosts of the end caps that give this article its title, so as to better understand their requirements.

When we talk about metallic structures we are referring to a series of systems made up of various metal parts. In many cases, they play a leading role in construction processes. On the one hand, they can function as the internal skeleton of a building, prepared to withstand certain forces. On the other hand, they can also be used as external frames, e.g. for facades, roofs, etc.

In either case, we are dealing with an area, namely construction, that deserves special attention in terms of safety, in at least two respects. First it is necessary to ensure that the work of operators is carried out with all the safeguards. But also that the finished assembly complies with all the safety requirements required on each occasion. And in both cases, there is no doubt that the involvement of external plastic end caps is vital.

Uses of external plastic end caps on steel structures

In view of what has been explained above, it is now time to answer the main question: What is the purpose of incorporating external plastic end caps into the metal structures we have described? Suffice to say that the transcendent importance of end caps stems from their relationship with the term “safety”.

Finishes to avoid accidents.

It is easy to imagine that when a metallic structure is installed, it is quite possible that they continue to exhibit certain dangerous points. This is the case, for example, for terminations where the metal is chipped or roughened after cutting. Or in places where the connections between one substructure and the other are located. On these occasions, end caps function as elements designed to cover these areas, preventing the possibility of scratches, cuts, etc.

Gripping and support points.

As part of a metallic structure, outer plastic end caps also play the role of grip or support. The plastic material used is resistant and very effective in preventing possible slippage. And in the case of FORTAPS the specific use of high and low-density polyethylene, thermoplastic rubber, or ABS (acrylonitrile butadiene styrene), ensures extremely high resistance. Therefore, its appropriate response to construction conditions, thermal variations, etc., is guaranteed. Such as the environment to which they will be subjected in the course of a very hard-wearing useful life.

Meanwhile these pieces, also thanks to the materials from which they are made, possess great advantages due to their high resistance to the exercise of force. This makes the end caps firm and solid supports.


In our catalogue you can find various types of external plastic end caps. And all of them with the guarantee of being made under strict quality controls. We take the utmost care in processes and materials to ensure your satisfaction. In addition, we also offer alternatives tailored to your specific needs.

End caps are our specialty, so we’re standing by ready to answer all your questions. Let’s talk!

Manufacturers of signage and street furniture

Manufacturers of signage and street furniture

End caps for manufacturers of signage and street furniture are a component that needs to be considered with special attention. Something that almost certainly goes unnoticed by most people becomes paramount for those in charge of planning and developing their placement over the entire extent of cities. Since they may ultimately be the ones who will answer for their adequacy and proper functioning in the public arena.

And therein lies precisely the key to their importance: the orientation of these items to community service and their use by citizens. This is something that manufacturers of certain types of signage are well aware of. As well as urban features that serve various uses in the daily life of the population.

Why are end caps necessary for signage and street furniture?

First of all, it is worth looking at some concepts, as they themselves can give us the answer to this question.

What do we mean when we talk about signage?

The term signage refers to a form of communication carried out by means of symbols, icons, colour codes or that are in some other way understandable by people. These are usually indications of routes, directions and guidance. But it also serves to provide other types of instructions.

Cities are full of signage, both outside and inside buildings. Although it is true that the latter are usually wall panels, adhesives for various surfaces, etc.

What is meant by street furniture?

On the other hand, street furniture consists of all those elements installed in the public highway, for the fulfillment of a range of purposes. But always linked to a form of community service. They are usually benches placed in streets, squares, parks, etc. In addition to bus stop shelters, planters or flower pots, litter bins, gel dispensers, etc., the following products are also available

What is the purpose of adapting end caps to these urban planning components?

In view of these descriptions, it is easy to appreciate that these objects, viewed as a whole, serve one main purpose: to serve the public. In particular, they are geared towards two aspects: their safety and well-being.

This is the factor that puts signage and street furniture manufacturers in a position of the utmost responsibility. With their products, they cater to fundamental needs. What’s more, they also contribute to improving the aesthetics and image of cities. For all these reasons, this industry knows first-hand the value of using the right end cap for every occasion.

Maintenance and resilience are the core properties of these outdoor components. Therefore, end caps must be components whose durability and resistance is a prominent feature.

What kind of end caps do signage and street furniture manufacturers need?

Most of the signage and street furniture that require the use of end caps are used outdoors. This means that the components, and therefore the end caps, are exposed to the inclemencies of the weather.

Seasonal, or simply diurnal and nocturnal, thermal change can pose a very difficult challenge to the street furniture and signage in an area. But if to this are added periods of rain, hail, heat waves and cold snaps, ice and humidity, the response of the materials has to match the rigours they face.

Every manufacturer knows that, in these circumstances, the best answer for signage and street furniture is rubber end caps. In addition to those manufactured from latex. Both are strong and provide the grip and safety required when using these devices. But it is also true that street furniture requires the incorporation of other types of components to ensure their safety.

Types of rubber stoppers and common uses

Types of rubber stoppers and common uses

The types of rubber stopper that exist on the market reflect the demand from manufacturers for a wide range of articles. And, ultimately, the needs of the end users who purchase these articles.

First it may be said that these components are characterised by a versatility that places them in a prominent position in the output produced by FORTAPS. Thus, they can be integrated into different types of structures, of which they become an inseparable part. Without them, the performance of these ensembles would be deficient.

Common uses of rubber stoppers

Their most common uses are evident both in the course of the day-to-day life of any individual, as well as in more professional or industrial fields. This wide range of uses is the main reason why their production is carried out in a stable and continuous manner.

However, despite this variety of uses, the truth is that they all meet the same requirement: to reduce the force of impacts. Therefore, to talk about the functions of these parts is to dive into the world of the laws of physics. And in particular, one concept must be kept in mind: kinetic energy. A term that refers to the energy possessed by bodies due to their motion.

All types of rubber stopper fall within this framework. Their main use is to absorb the kinetic energy contained in the impact of one object on another. For this reason it is also necessary to take into account the resistance of their materials, whether rubber or thermoplastic rubber, etc.

Fitting the appropriate rubber stopper for a specific case means a major attenuation and cushioning of the shock. This is something that the producers of certain articles are familiar with at first hand. But, on the other hand, it goes unnoticed by the vast majority of the population.


In general, it can be said that the functionalities of rubber stoppers can be divided into three. And here we include their use for shock absorption. A utility that can be assimilated to safety and anti-slip functions. But they also serve aesthetics, providing more harmonious finishes or hiding certain elements.

Finally, their hygienic properties are indisputable. Functioning as a cover that prevents dirt from entering the interior of tubes and structures.

Everyday actions such as opening a door can change completely if we do not rely, in its execution, on one of the types of rubber stoppers suitable for the circumstances. Perhaps it is easier to see this with the help of some examples from the FORTAPS CATALOGUE.

Types of rubber stopper

Having clarified the different functions that rubber stoppers can perform, here are some examples from our range.

Door stop

Model reference 60 from FORTAPS leads of a set of stoppers corresponding to pieces manufactured in a standard black colour, with varying diameters. They start with a minimum (15) and go up to a maximum (40), hence their different reference numbers.

This rubber stopper is mounted by means of an internal thread system. It is therefore suitable to be screwed, as its name suggests, behind doors. And there absorb the impact of a forceful opening, without damaging walls or other surfaces.

Stoppers for crutches and walking frames

External rubber stoppers are an indispensable accessory for sticks, crutches and walking frames. Models such as the one denominated by reference 50(reinforced exterior), placed at the end of the tube, serve to support and cushion the impact of the steps and the individual. At the same time, they help to avoid possible slipping. And in this way, they contribute to maintaining the individual’s safety.

Stoppers for machinery systems

The mechanical systems that drive industrial processes exert powerful, repetitive movements. In this context, the inclusion of specific types of rubber stoppers is essential to cushion shocks and noises. As well as to reduce wear and tear in certain areas.

Furniture stoppers

Avoiding slipping, unnecessary noise or marks on surfaces are just a few aspects at the top of a long list: the one that defines the relationship between different types of furniture and rubber stoppers. This makes these types of rubber stopper one of the best known and most demanded by both furniture manufacturers and their customers.

End caps for wooden furniture: what should they be like? Four requirements

End caps for wooden furniture: what should they be like? Four requirements

End caps for wooden furniture are essential elements for achieving the best end-user experience. So it’s crucial to include them in the manufacturing and assembly line for certain types of wooden furniture. Especially for articles that are going to be used in a way that involves some kind of movement or dragging. Whether you manufacture wooden furniture for private use, or for department stores or establishments linked to the hospitality industry, this article may interest you: let’s take a look at the main characteristics of these end caps.

What are the uses of end caps for wooden furniture?

As you know, end caps are protectors used to safeguard the legs of chairs, tables or other types of furniture, with different purposes. The characteristics of end caps for wooden furniture and the likelihood of them doing their job properly are directly related issues. So as a preliminary step we’re going to run through a quick review of the functionalities of end caps for wooden furniture. In this way we’re confident it will be better understood what characteristics these components should have.

Avoiding noise

It happens to all of us that when we stand up, sit down or approach a table, for example: we drag our chair over the surface where it happens to be located. A wooden chair with end caps fitted to its legs will eliminate these inconveniences involved in its day-to-day use.

Floor protection

As well as preventing noise from wooden furniture, they also prevent scratches and marks on the floor. This is why it makes sense to choose the most appropriate option for the type of floor the furniture is going to be used with.


Ensuring safety in the use of its products is the top priority of any furniture manufacturer or distributor. And end caps are a perfect product for this. Because, thanks to the way they fit, you’ll succeed in minimizing any kind of risk. Otherwise, you’ll end up with possible slips or falls.

Aesthetic solutions

Articles of furniture not only fulfill a utilitarian purpose. They are also decorative elements. And that’s why you have to take care of every last detail, including the extremities of the legs. Looking for a smooth and stylish finish.

Main characteristics of the end caps for wooden furniture

The characteristics to be met by end caps for wooden furniture must be linked to the functional purposes we’ve just told you about.

Adaptability to different floors

It is important to choose the end cap that best fits the characteristics of the floor on which the furniture will be placed. Because every floor, whether it’s parquet, ceramic tile or carpeted, has different needs. For example, if you’re going to use the furniture on a parquet floor, your best bet is rubber end caps. Since we’re dealing with a rather delicate surface. On the other hand, if the wooden furniture is to be used on a carpet or carpeted floor, it is important to ensure that the legs do not sink in. And in this case, the end caps that offer the best results are harder.


End caps for wooden furniture must be highly resistant. This will enable them to fulfill their goals in the best way and for the longest time possible. In addition, they will also help to increase the resistance of the furniture itself. To achieve that toughness and durability it is advisable to choose very resistant materials, such as polyethylene, of low or high density, depending on the needs of the items of furniture.

With the capacity to provide harmony to the whole

We have already said that end caps for wooden furniture are used for aesthetic reasons. They provide a more harmonious finish to the whole structure. And they achieve this by softening the finishes on the legs. But they can also do so by providing a touch of colour. Because end caps are usually made in neutral colours, such as white or black. But alternatives are available, such as those included in the  RAL range of colours.

Perfectly adjustable to the tube

This characteristic is fundamental. Because if it is not met, all the others will also fail. Bear in mind that an end cap that does not fit perfectly on the tube of the leg can cause huge damage, to the furniture itself and to the floor. More seriously, it would greatly increase the accidents suffered by furniture users.


The end caps for wooden furniture that we manufacture at FORTAPS meet all these characteristics to perfection. In addition, we adapt to your needs by offering tailored solutions. Always under the quality parameters of the ISO 9001:2015 standard.

Main success stories involving end caps for multiple-user furniture

Main success stories involving end caps for multiple-user furniture

End caps are a solution that goes beyond the merely convenient and enters the realm of the indispensable. This is all the more so considering the inherent needs of some manufactures.

There are certain elements whose particular characteristics affect the need to use this type of protection. We’re talking about items belonging to the category of multiple-user furniture.

These days, manufacturers of this type of furniture know their specifications very precisely, and they refer not only to the object itself. In particular they relate to those derived from how it’s used, as the name indicates: by multiple users.

In any case, it’s worth underscoring all the benefits rubber end caps tailored to these structures can provide.

Why is there a need for rubber end caps? Who requires them?

Knowing the needs of our clients is the best way of gaining an in-depth understanding of what they lack. And, further down the line, the results of our input into their production.

It was precisely in the search for such answers that a stellar product came into being in the FORTAPS Technical Office in 2010, one that today has established itself as a real success: the reinforced end cap, especially for multiple users.

We seek to ensure the satisfaction of our direct customers. And we are aware that the only way to achieve this is to collaborate with them so that they can provide the consumers of their products with the finest finishes. Thus, only by optimizing the end-user experience can we ensure a job well done.

Who needs reinforced end caps, specially designed for multiple users?

All furniture manufacturers understand the importance of installing this type of protector, end cap or finish cap on their products. But it is true that there are certain sectors in which this need is even greater. These are manufacturing activities subject to specific regulations on materials and safety.

Among them, the manufacturers of furniture designed for the hospitality industry and restaurants, as well as for schools and hospitals, the main recipients of this product.

Why do they need them?

At FORTAPS we long ago realized that these producers needed elements resistant to wear; parts that were easy to instal. And that could, at the same time, adjust easily to the shaft.

The increasing demand for them is no mystery. These are products designed for very specific sites where they will be used simultaneously by multiple users. Therefore, in addition to the specific characteristics linked to the use of any piece of furniture at home, there are also those related to its location.

First of all think, for example, of the annoying noises or marks that a chair can produce on the floor of the venue in question. Then imagine the marks and noises produced by all the chairs contained in a single venue, such as one of those previously mentioned. Clearly the problems they can cause are multiplied exponentially.

Benefits of using rubber end caps

The fitting of plastic protectors, adapted to the needs of each piece and circumstances, is a guarantee of improved user experience. These are some of the benefits they bring:

  • They function as noise-cancelling devices. Moving furniture around on the floor is no longer a nuisance.
  • They prevent marks on all manner of surfaces. Nor do they leave blemishes or traces. And, both on this point and the previous one, the most appropriate material can be chosen (whether rubber or plastic) to achieve a perfect match to the flooring material.
  • The aesthetic advantage. They bring an added elegance to the appearance of the tubular legs.
  • They have an impact on safety. They prevent slips and falls.


At FORTAPS we can offer you a comprehensive catalogue of plastic protectors, of different shapes and diameters. In addition to the possibility of requesting tailor-made solutions, made to order. As suppliers, we guarantee you an uninterrupted flow of stock, ensuring the continuity of your production.
