This Harken 57 mm Carbo Ratchet block is developed for efficient line handling under high loads, where control and grip are essential.
The ratchet function provides extra friction on the line, helping the sailor trim with more control without losing the feel of the load.
The block features an 8-sided, Hardkote-anodized, Teflon®-impregnated sheave that provides 1.5x holding power with 180 degrees of wrap.
