Harken Big Bullet Block 134

Low-friction Bullet blocks lead control lines aft. 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. Delrin® ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection. Wire Bullet blocks use roller bearings to carry higher loads and feature Hard Lube-anodized aluminum sheaves for strength and corrosion resistance. Mast exit blocks with cams are used for halyard controls and under boom mainsheets. Use for: Outhauls Vangs Barberhaulers Cunninghams Traveler controls Furling line leads Flag halyards
