Harken recommends equipping every system with Carbo lead blocks for safe furling from the cockpit. A 7402 ratchet maintains tension when spooling so the unit can furl smoothly and easily. The 7403 outboard assembly allows furling line to travel outboard of the stanchion to keep the sidedeck clear. Block mounts with a strong four-screw clamp without removing the stanchion or lifelines. Use the 7401 40 mm block on the bow pulpit as an inboard lead. Both the 7401 and 7402 have ball and socket bases to align blocks for smooth leads aft.
