Strong, dependable, and exceptionally free running, 29 mm diameter Bullet blocks are the foundation of the Harken line, with a vast library of hardware choices available to complement your boat’s style.
They are compact and lightweight, with fast trim and release under high or low loads. A range of styles lets these blocks adapt to almost all control line applications.
Classic blocks come in dozens of configurations and are ideal for almost every trimming task.
Ball bearings, sheave, and sideplates are UV-stabilized with carbon-black for maximum protection. Stainless steel straps reinforce blocks and resist corrosion.
