Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing.
Nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Machined aluminum sheaves are Hardkote anodized for strength and corrosion resistance. Eight facets hold line securely. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection.
The 57 mm switchable ratchets provide precise on/off control with accessible, easy-to-operate on/off switches on both sides of the block. For the ultimate system, mount a switchable ratchet in the cockpit and a boom-mounted Ratchamatic® directly above for double holding power in heavy air and a freerunning mainsheet when it's light. The 57 mm provides up to 10:1 holding power.

HARKEN 57MM CARBO RATCHET BLOCK W/CAM CLEAT
It makes a clicky noise that goes through my ears and into my body... very much like a dirty ASMR video but without the guilt afterward. Also, it stops the sheet from going away from me when I use it so win win.
