DESCRIPTION The Model # US-5038 is a small wire grabbing device that follow a worker?s movement up and down a vertical lifeline. If a fall occurs, the cable grab locks on the cable and reduces the possibility of serious injury. An energy absorbing lanyard is used for connection between the cable grab and worker?s harness to reduce the forces generated during a fall and to insure compliance with OSHA?s maximum force requirements. BEFORE USE Inspect the rope grab for any damage, dirt, oil, grit, paint, etc. Refer to the ?Cleaning? section on the page. Make sure the lifeline is the proper type and size. (3/8? diameter Stainless steel or galvanized 719 aircraft cable (non-lubed) with a minimum tensile strength of 8,000 Ibs.) Tie off the bottom end of the lifeline vertically below the anchorage point to eliminate excess slack.
