Harken Carbo Blocks 29 mm / Two Fix

The compact 29 mm Carbo Block is extremely powerful, suitable for use as a mainsheet block on small dinghies like the Opti or as low-friction control blocks on boats of any size. The two and three-part blocks feature U-Lock, which allows the swivel to be fixed in a frontal or lateral position when needed. The compact, robust clamp arm of the three-part block makes it suitable for high-load 5:1/6:1 purchases. The horizontal block occupies only a small area and has drainage holes. High-strength, tilting guide blocks with clamps are used for control lines on smaller keelboats and as "head knockers" on dinghies and beach cats for direct sheet control from the boom. The hole spacing and rivet size match those of the Classic versions, making upgrades easy. The clamp is reversible for upward or downward clamping. Applications include boom vangs, downhauls, barberhaulers, Cunninghams, traveler controls, and flag halyards.
