40mm Single Control Line Footblock

Lewmar’s Synchro footblocks use alloy cheeks, fixing isolators and to prevent sealant from getting into the sheave, a molded base plate. All sizes are available in standard and jamming formats and can be stacked to form a double footblock. The 40mm control line footblocks come with a stainless-steel base plate and can be used as miniature organizers or deflectors for lines being returned to the cockpit. Jamming footblocks are designed to temporarily held a sheet while it is transferred to another winch.
