Hand-hold your loaded lines and experience controlled releasing with Harkens 57mm Carbo Ratchet Blocks.
Their machined aluminum sheaves have eight facets to hold line securely with 10:1 advantage when the block is ratcheting. Recessed switch allows on/off control for the ratcheting mechanism.
These blocks are primarily used for main, jib and spinnaker sheets, traveler controls and foreguys. Sheave diameter is 2 1/4 in (57mm).
The load ratings for blocks with cams are based on the cams strength.
Note: For the ultimate mainsheet system, mount a switchable ratchet in the cockpit and a Ratchamatic on the boom to allow double holding power in heavy air and to ensure the mainsheet runs out freely in light air.
This Series 55 Ratchet Orbit single block is the only one in its class that gives you auto and manual engagement modes. It provides up to 21:1 holding power and enables you to release sheets smoothly. That's nearly double the holding power of its nearest competitor.
The sheave has twelve, rather than eight, gripping faces, which distribute the load and minimize rope wear. Use it for mainsheet and spinnaker sheet systems on dinghies, sportboats, and small keelboats; halyard, vang, and backstay applications on boats up to 26' (8m); and control line applications on larger yachts.
Make sure you have a standard Dee shackle with a slotted pin of 5/32 in diameter for attachment.
