The Wurtec ratchet beam clamp is a safe, portable tool that provides a secure anchor point in hard to reach places. It conforms to OSHA 1926.502, and is an approved anchor point for fall protection for up to two people. The ratchet beam clamp can also be used for hoisting and can support up to 3 tons (6,600 lbs). To use, attach a lifeline or safety line to the safety bolt at the bottom of the clamp, then open the jaws of the clamp. Position the clamp on the end of the 11-115 telescopic attaching rod and lift towards the desired location. When the clamp trigger comes in contact with the beam, it snaps closed and into a locked position. The ratchet beam clamp works on any beam with a 4-8” wide flange.
