A limiter knot is required with all SAS lifelines. Tie the knot below the rope grab position to gauge free fall length and prevent the grab from sliding off the rope end. Keep the lifeline away from sharp edges, cutting tools, electrical sources, open flame, hot asphalt, adhesives, solvents, paints, and chemicals that damage polyester, and never tie lifelines together or wrap them around framing as an anchor.

Typical Applications
Installation Overview
Rigging figures, rope grab installation, and the length of fall plan worksheet are in the SAS Lifeline Manual 05-2024 linked below. The basics:
- Connect the snaphook A-end only to an OSHA or ANSI compliant anchorage device specified for fall protection use.
- Install your rope grab with the direction arrow or prussic wraps oriented per its manual, toward the lifeline A-end.
- Connect the rope grab to a personal energy absorber, and the absorber to the harness dorsal D-ring.
- Tie a limiter knot below the rope grab position to gauge free fall length and prevent disengagement at the rope end.
- Calculate the length of fall: free fall plus grab deceleration, absorber deployment, harness stretch, and a 24 inch clearance margin.
- Perform the snaphook function tests and lifeline inspection before each use.
Inspection and Retirement
Inspect before installation and each use, with documented annual inspections. Remove the equipment from service when any of the following apply:
- Strands are cut, hocked, abraded, or show heat damage.
- The eye thimble is deformed or missing, or the swage is cracked or loose.
- The PID or inspection label is missing.
- The limiter knot is missing, or a knot is tied above the rope grab; correct before use.
- The snaphook fails the gate lock, gate open, or gate close function tests.
- The lifeline was subjected to a free fall or has exceeded its service life.
Tag equipment removed from service to prevent further use until inspected by a qualified or competent person.
