The P51104041 is a Grade 80 alloy safety swivel hook with a 6,000 lb working load limit. The swivel end lets the cable lay flat against the hook even under load shifts, and the integrated safety latch keeps the cable from popping out of the hook throat.
What's the difference between working load limit and breaking strength?
WLL (6,000 lb) is the safe operating load — the value to design rigging around. Breaking strength (24,000 lb) is the ultimate failure point, with a 4:1 safety factor built in. Always rig to the WLL, never the breaking strength. The breaking strength is your margin against shock loads and dynamic peaks, not headroom for harder pulls.
