Guardian L392 SA shock absorbing lanyard is constructed with an anchorage end that can accommodate different types of structures. The lanyard consists of 1-3/4 in. wide polyester web attached to a shock absorber that attaches to a full body harness through a double locking snap hook.  The device will activate when a force of approximately 675 lbs. is applied, and will continue as long as the force of fall arrest meets this value.
