Harken's Classic Bullet Blocks are low-friction blocks that 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.
Derlin® 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.
