Harken 57mm Carbo Ratchamatic HTE Block, Swivel, 2x Grip
Harken 57mm Carbo Ratchamatic HTE 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. The spring on the HTE (high-threshold engage) version of the 57 mm Carbo Ratchamatic blocks was made stiffer to delay 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.
