40mm Carbo Ratchet Cheek Block
Harken 40mm Carbo Ratchet Cheek Block for clean deck organization and 180° line angles.
Carbo Ratchet cheek 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 40mm blocks are for jibsheets and spinnakers on small dinghies.
The 40mm, 57mm and 75mm Carbo cheek blocks 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.
