Control loaded lines with ease
The 57mm and 75mm Carbo Ratchamatic blocks are adjustable for use in 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. Great for asymmetrical spinnakers when you need tough holding power and a quick release.
