MSA's Latchways® Freestanding Constant Force post provides assured worker safety at height where there is an occasional or temporary requirement to access flat roofs or structures.
At the heart of the system is MSA’s unique Constant Force Technology. The Constant Force Post is contained within an anchor device consisting of a galvanized steel frame and galvanized steel weights bolted in a circular formation onto rubber coated base weights. In the event of a fall, the Constant Force post deploys to limit the load on the system while the weights simultaneously create a friction anchor between the unit and the roof surface.
