Effectively reduces peak loads on an anchor in rescue and rigging systems. Designed as a stitch ripping device with extremely consistent activation and absorption accuracy (+-5%). Very useful in documenting maximum loads in a given rescue and rigging situation such as in highlights and mechanical advantage hauling systems. It can be ganged to double the activation force. Single unit activation >500 lbf. (2kN+). Double Ganged/Parallel unit activation >1000 lbf. (4.5kN+). Ultimate strength 5000 lbf. (22.2 kN)/ Single Unit.
