Designed to relieve the negative effects of suspension trauma, DBI/SALA & Protecta’s Suspension Trauma Safety Strap allows a suspended worker to stand up in their harness to relieve the pressure being applied to the arteries and veins around the top of the legs. The strap, which allows for improved circulation in the legs, is easily installed to most harnesses.DBI/SALA & Protecta, Red Wing, MN.
