Lewmar Synchro blocks are engineered for speed, efficiency and superior handling. We use 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.
Standard and jammer options can be double stacked The upper sheave should not be loaded beyond 60% of WLL.
Lewmar 60mm Synchro Single Aluminium Footblock.
- Standard and jammer options can be double stacked.
- Two-step jammer action keeps lever close to side of the block.
- Optimised jammer shape holds line central on the sheave.
- Tough alloy cheeks.
- Synchro sheave loads match the same sized blocks.
Applications
Plain bearing blocks are typically used for heavy and static loads in:
- Halyard tuning.
- Mainsheet systems.
- Mast foot block.
- Mast head blocks.
- Boom vangs.
