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. Use the 2634 with a 402 or 403 swivel arm for a versatile two-speed mainsheet system.
