Harken 38mm Double Sheave Big Bullet Block

Low-friction Harken Bullet blocks lead control lines aft, built compact and lightweight with fast trim and release under both high and low loads.

A range of styles across the Bullet line lets these blocks adapt to nearly any control line application, from a simple aft lead to part of a more involved purchase system.

Rated to a 600-lb maximum working load, the double sheave configuration handles more line and higher loads than a single sheave in the same compact footprint. See what else we carry in sailing hardware.
