The Checkmate STSS safety harness trauma strap is designed for anyone working at height as it helps to mitigate the effects of suspension trauma (which can occur in as little as 15 minutes) in the event of a fall. The trauma strap allows better blood flow and reduces fatigue by allowing the fallen worker to assume a standing position and relieve pressure on the lower extremities. The Trauma Strap is easy to adjust, and its low profile keeps it out of the way during work.
