Lewmar Synchro Footblocks
Lewmar Synchro Sailboat Footblock from Mauri Pro Sailing
For low-load Lewmar footblocks, you'll want composite sheaves and friction cams. For high load, alloy sheaves and spring cams. The jammer holding load is no more than 300 kg / 660 lb. Be sure you don't load the upper sheave beyond 60% of the Safe Working Load.

Synchro blocks from Lewmar are engineered for speed, efficiency and superior handling. These blocks suit a range of purposes from performance cruising yachts to specific high-load low-movement applications on racing sailboats. Lewmar uses a combination of scientifically optimised block geometry, a Free-Spin bearing and self-aligning head to reduce friction and increase efficiency by up to 40% over budget blocks on mainsheet systems.

Sheaves run on Torlon rollers with dual Delrin ball side thrust races. Alloy sheaves, alloy bayonet cheeks for simply servicing. Safe working loads are quoted for the whole assembly.
