Harken Bullet 38mm Pivoting exit Cam-Matic 150

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. Pivoting exit blocks with cams are often used for halyard controls and as “head knockers” for sheeting directly from the boom. The 140 has a high safe working load and is designed for spar-mounted halyards and control lines.
