Harken's Carbo Ratchet Blocks allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. The 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 Hard Lube-anodized for strength and corrosion resistance. Eight facets hold lines securely. Ball bearings, sheave, and sideplates are UV stabilized with carbon black for maximum protection.
The 40mm Ratchets are ideal for jib sheets and spinnakers where size and weight are critical. Other common uses are mainsheet fine-tune, vangs, travevler controls, genoa leads and foreguys.
The 2613 is always in ratchet mode. The shackle can be locked in front or side positions, or left unlocked to allow the block to spin freely. Cam assembly adjusts and locks in a wide range of positions for crew accessibility.
