Harken Bullet Block 29mm In-Line Exit

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.

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.
