Harken recomends equipping every furling system with Carbo lead blocks for safe furling from the cockpit.
The 7403 outboard assembly allows furling lines to travel outboard of the stanchion to keep the side deck clear.
The UV stabilised Carbo blocks run on ball bearing sheaves for fast trimming under any load.
The block mounts with a strong four-screw clamp without removing stanchions or lifelines.
