Freestanding Constant Force® Post

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.

  • Applicable where there is an occasional safety at height requirement
  • Suitable for flat roofs (maximum 5° pitch)
  • Can be used on a wide range of roof surfaces including concrete, single-ply membrane, bituminous membrane, sanded and stone chipping asphalt, and steel profile
  • No need to puncture the roof membrane to fix the system

  • Each anchor device protects a single user
  • Conforms to OSHA 1910.66 App C & 1926.502 clause (d) (15)
