ACRO Parapet GuardRail System Bracket and Post #12090

The Acro parapet guardrail system allows contractors to setup fall protection quickly and safely without additional hardware. This system does not penetrate the building or roof substrate, and has a safety bracket that simply locks onto parapet with adjustable hand screw and cross rails that require no tensioning. This parapet wall bracket comes with a guardrail post holder and a second post to hold two 2' x 4' boards. When the 2ft x 4ft boards are inserted through the post slots in conjunction with a 2 x 6" toe board, it forms a safe continuous guardrail around the roof edge that can be easily setup and taken down to move to the next job where fall prevention guardrail is needed.
