**Includes RH fasteners and mounting pad.
Ratchet blocks are hand and crew savers. The eight-sided sheave grips loaded
sheets with up to 15: 1 holding power. Ratchamatic blocks spin freely in both
directions under low load. At higher load, ratchet engages, providing holding
power. As the load decreases, the ratchet shifts back into light air mode and
free spins. Unloaded main and jib sheets run out freely during mark roundings
and asymmetrical spinnakers run free during jibes.
