Freestanding Roof Edge Protection

OSF’s Freestanding Roof Edge Protection is a counterbalanced handrail system that has been providing a vital protection solution for worker safety at height for over 15 years. It 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.

Our Roof Edge Protection system can also be used to provide a guarded walkway across a roof or individual protection around hazards such as sky lights and air conditioner units.

OSF offers free help and advice to establish the required materials needed for any installation. All items are in stock and ready for next day delivery.
