Harken 75mm Carbo Ratchamatic Triple Block with load-sensing, automatically engages the ratchet when the load increases.
Carbo Ratchets allow sailors to hand-hold loaded lines and offer a balance between holding power and controlled easing. Lightweight Carbo Ratchets are available in 40mm, 57mm, and 75mm sizes. All the Carbo Ratchets feature a recessed On-Off switch that is easily operated from either side. The 40mm cam-arm versions work in ratchet mode only. Commonly 75mm blocks are for mainsheet and asymmetric spinnaker sheet trim on larger keelboats.
The 40mm, 57mm, and 75mm Carbo Ratchamatic® are adjustable for many applications and weather conditions. The load-sensing ratchet block rolls freely in both directions under low loads and then engages the ratchet automatically as loads increase. With a 180-degree wrap, you get a 10:1 holding power.
Note: Special Order Only
