Product Description
Harken 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 Hardkote-anodized Teflon® impregnated aluminum sheaves for strength and corrosion resistance. Mast exit blocks with cams used for halyard controls and under boom mainsheets. Pivoting exit blocks with cams are often used for halyard controls and as ''head knockers'' for sheeting directly from the boom.
Use for: Outhauls Vangs, Barberhaulers Cunninghams, Traveler controls Furling line leads and Flag halyards.
