57 mm triple ratchet blocks with clamp

Carbo Ratchets allow the sailor to hold a sheet under load by hand, for the right balance of holding power and controlled yawing. The nylon resin stringers are reinforced with densely layered long glass fibers to create a compact block with a high load-to-mass ratio. The milled washers are Hard Lube anodized for strength and corrosion resistance. The eight bevels hold the sheet securely. The free-running ball bearing, sheave and cheeks are blackened for maximum protection. 57 mm
