57 mm Ratchamatic Block Swivel
The Carbo Ratchamatic is a load-sensing ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless.
Standard grip: medium/light air; 10:1 holding power.
DO NOT use Harken equipment for human suspension unless product is specifically certified and labeled for such use.
