57mm Carbo Ratchet Stanchion Block

Harken recommends equipping every system with Carbo lead blocks for safe furling from the cockpit.

Use the 7401 40 mm block on the bow pulpit as an inboard lead.
A 7402 ratchet block helps maintain tension when spooling so the unit can furl smoothly and easily.
Both the 7401 and 7402 have ball and socket bases to align blocks for smooth leads aft.
The 7403 outboard assembly allows furling line to travel outboard of the stanchion to keep the sidedeck clear.

These blocks mount with a strong four-screw clamp without removing the stanchion or lifelines.
