The Guardian Fall Protection Chain Positioning Lanyard (also known as a chain or rebar positioning device) 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.All chain assemblies are adjustable, and several connector options are available.
