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.
