LEWMAR
Synchro Footblocks

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.

  • Standard and jammer options can be double stacked
  • Two-step jammer action keeps lever close to side of the block
  • Stainless-steel hollow cast jammer, holds fast without tearing the line
  • Optimized jammer shape holds line central on the sheave
  • Tough alloy cheeks
  • Synchro sheave loads match the same sized blocks
  • Twin fixings with inserts
  • Wide head for a solid base, block will not “roll” on the deck
  • Molded base plate with recess to hold sealant around fixing screws and prevent ingress onto the bearing and sheave
