The basic concept of the system is simple, the Roller Cups are designed to be too large to get a hand grip on. The cups are threaded onto a central spindle and rotate independently to form an unstable barrier, making it very difficult to climb.

The system is widely specified in the UK as the "Preferred - Anti-climb System" for use in and around schools or other areas where children congregate.

Double Roller Barrier was recently used in a temporary housing hostel in London which had apartments and open spaces on the 6th floor, this meant families with children could not be housed there due to the risk of inquisitive climbers falling from the edge. With cranked brackets being pointed inwards and fixed to the face of the wall, it not only made access to the top of the wall impossible, it means that any attempts to jump up were thwarted in a non-aggressive manner.

Double Roller Barrier consists of a series of independently rotating cups mounted on a central shaft (extruded aluminium tube) and supported at 2 metre intervals with suitable brackets. Shaft lengths can be quickly and easily joined together using a joining spigot, to form longer runs (or cut to shorter lengths if required).

The range of standard brackets available from stock, will allow the system to be easily installed on most types of walls, fences, gates, roofs or building fascia’s, however where required, bespoke brackets can be manufactured for those odd environments where the standard brackets would not be suitable.
