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.
