HARKEN 75mm Carbo Ratchamatic Single Block with Becket and Cam, 2684
Harken 75mm Carbo Ratchamatic Block with Cam arms can be locked in more than five positions for fair leads.
Carbo Ratchet blocks allow sailors to hand-hold loaded lines and offer 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 jibsheets and spinnakers on larger keelboats.
The 40mm, 57mm and 75mm Carbo Ratchamatic® is adjustable for many applications and weather conditions. The load-sensing ratchet block rolls freely in both directions under low loads, then engages the ratchet automatically as loads increase. With 180 degree wrap, you get a 10:1 holding power.
