What is a Roller Barrier Run?

Posted by Tony Goldstone on

To help people determine exactly what they need when devising their Roller Barrier protection installation we’ve produced this video to clearly explain what a Roller Barrier run is.

If you have already viewed some of our other Roller Barrier videos you will know that Roller Barrier is a totally non-aggressive anti climb system that uses side-by-side rotating Roller Cups threaded onto a robust central shaft. The Roller Cups are specifically designed to be too large to be gripped, preventing would-be intruders or climbers from overcoming the barrier. But importantly, unlike aggressive, spiked anti climb devices, there is no potential for injury.

Roller Barrier is a versatile, adaptable security system that will fit the varying contours of any wall, fence, roof, gate or other structure where safe anti climb protection is needed. The system is now being used in a wide variety of applications around the world to provide cost effective, non-aggressive anti-climb protection. 

What is a Roller Barrier Run?

The Roller Barrier anti climb system consists of a number of key components including the Roller Cups, the Roller Barrier central shaft, support brackets, end fixings and suitable fastenings to attached the brackets to whatever structure is being protected.

A Roller Barrier run refers to a straight-line section of Roller Barrier where there are no sharp variation in height and no deviations from a straight line along its length. Installations involving step changes in height or sharp changes in direction need to be split into separate straight sections, each of which would be a separate Roller Barrier run.

There are no upper or lower limits to the potential length of a Roller Barrier run. For longer runs Roller Barrier support brackets need to be installed at regular intervals of around 1 to 1.5 metres but Roller Barrier also works over short runs of under 1 metre where necessary. Roller Cups are 100mm wide so ten of these are needed for every 1 metre of Roller Barrier Run. 

Multi-Row Roller Barrier

Another important aspect of Roller Barrier installations is how they can be made up of one, two or three rows of Roller Barrier.

A single row of Roller Barrier often provides adequate protection but double row Roller Barrier is ideal for situations where additional height is beneficial. Trigard Roller Barrier uses 3 rows of Roller Barrier and is particularly useful for protecting lower-level structures from potential climbers. These multi row systems use specially designed support brackets.

Roller Barrier Run Examples

Here’s an example of a single row Roller Barrier installation involving multiple Roller Barrier Runs.

The image shows how the fencing changes height to the right hand side of the gateway and how Roller Barrier is enhancing anti-climb protection. In this image there are clearly 3 x separate straight Roller Barrier run sections.

In this next image you can see how a long, straight run of green Roller Barrier is providing anti climb protection for a busy railway line in an area close to where people live and children play.

This next image shows a double-row Roller Barrier installation at a busy railway station.

As the image shows, the double row of Roller Barrier significantly increases the height of the boundary fence, protecting the railway site from unwanted intruders and ensuring passengers are routed via safe gateways. 

A double row Roller Barrier installation requires twice as many Roller Cups as a single run along with appropriate double row support brackets.

This next image shows a short Roller Barrier run of Trigard triple-row Roller Barrier.

Trigard Roller Barrier is especially useful for protecting low level structures and equipment from unwanted climbers. A triple row installation like this requires three times as many Roller Cups along with appropriate support brackets.

Roller Barrier Shafts and Terminations

The support shafts used by Roller Barrier can be easily cut to fit any Roller Barrier run length. Each end of the Roller Barrier support shafts for every row must be terminated with a security fixing to prevent the unauthorised removal of the Roller Cups. The Shefal security end collar and cap fixing is widely appreciated for its aesthetic appearance ease of installation.
