Harken recommends equipping every system with Carbo lead blocks for safe furling from the cockpit. Use the 7401 or 7407 block on the bow pulpit as an inboard lead. 7401, 7402, 7405, and 7407 have ball-and-socket bases to align blocks for smooth leads aft.
Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing.
Nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Machined aluminum sheaves are Hard Lube-anodized for strength and corrosion resistance. Eight facets hold line securely. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection.
