HARKEN 2633 

Cheek Block - Carbo Ratchamatic® - 57mm

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. Unloaded main and jib sheets run out freely during mark roundings, and asymmetrical spinnakers free instantly during jibes.

Ratchet engagement may be adjusted to a higher or lower load, according to strength and sailing style. The Carbo Ratchamatic® cheek block mounts on either port or starboard.

Use for:
  • Main / jib sheets
  • Asymmetric spinnakers


Includes RH fasteners & mounting pad
