ABSTRACT:
A safety rail system for installation about the perimeter of a rooftop work site comprises a plurality of stanchion-supporting bases for attachment to existing building structure, a plurality of stanchions removably held by the bases and having cable-receiving links thereon, and a pair of wire rope cable safety rails supplied by a pair of winches fixed to at least one of the stanchions. The bases include a pair of plate members connected by a hinge for adjustable attachment to a vertical wall surface of the building and another structural surface forming an edge with the vertical wall surface. A vertically extending sleeve is fixed to the plate member which attaches to the vertical wall surface of the building for slidably receiving a bottom portion of a stanchion, and a transversely extending locking pin is used to retain the bottom portion of the stanchion within the sleeve. The safety rail cables are unwound from their respective winches and connected to the stanchions using the cable receiving links, then tensioned using the winches.
