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 Cheek Block is also switch-controlled. The 40mm cam-arm versions work in ratchet mode only. The 40mm, 57mm, and 75mm Carbo Ratchamatic is adjustable for many applications and weather conditions. This 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.
