• 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
• Pivoting exit blocks with cams are often used for halyard controls and as "head knockers" for sheeting directly from the boom.
