The Guardian® Rebar Chain Assembly (Standard Style w/ Non-Swivel Double Locking Snap Hook with Clevis Pin) is perfect for Work Positioning applications on rebar structures. Its double legs allow workers to lean away from walls, while keeping their hands free to perform any necessary work. To function correctly, it must be used in combination with a full-body harness with side positioning D-rings, so that both snap hook components can be properly attached. The rebar chain assembly is a very high quality fall protection positioning lanyard.
