Harken 57 mm Ratchamatic® HTE Carbo Air® Block — Swivel, 2x Grip

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.

Harken engineers altered the design of the 57 mm auto-ratcheting Carbo Ratchamatic blocks to add a stiffer spring to the HTE (high-threshold engage) version. This delays the point where the ratchet engages, allowing the block to run free more of the time. The ratchet function engages at higher loads to allow the old kite sheet to run free for crisper gybes.

2x grip: big breeze/steady: 20:1 holding power.
