Alvin Freestand


Alvin Freestanding Roof Edge Protection is a counterbalanced guardrail system designed in accordance with BS EN 13374 : 2013 as a Class A protection system, that provides protection for worker safety at height. With no penetration or damage to the roof, the freestanding system is easy and quick to install and can be used on virtually any flat roof or up to a gradient of no more than 10 degrees.

Our counterbalanced system operates on a curved PVC weight, which does not damage the integrity of the roof surface. A galvanised malleable iron foot, with protective rubber base, supports the handrail post.

The system features 1100mm tall factory preassembled uprights that include open cradle fittings allowing the handrail tube to be quickly dropped into place, speeding up assembly and saving cost. In addition to counterbalanced arms the system uses key clamp components that make it quick and easy to install.

The wide range of available components enables the system layout to be configured to ideally suit the collective protection need. The posts can be spaced at a maximum distance of 2 meters apart.
