Harken 75mm Carbo Ratchamatic Flip Flop Block w/Cam

The Carbo Ratchamatic® is a load-sensing ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless.

Small Boat Flip-Flop blocks pivot around the line axis to keep the line close to the deck. Hinged construction allows for various lead angles.
