Work Positioning systems will hold and sustain you at a specific work location, limiting any free fall to two feet or less. Rebar Tying and Concrete Wall-Form Work are typical applications. For maximum security, each work positioning system includes a Delta No-Tangle full body harness connected by chainor web rebar assembly, or a rope or web lanyard. A workseat can also be added for additional support. A carabiner or snap hook connector is used to fasten to the anchorage, generally rebar or a support structure.
