Lewmar's 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.

Each component is perfectly synchronised with the movement of the rope, providing you with an easier, smoother transfer of power from deck to sail and less wear on your rope.

Stainless steel strap for improved strength and longer service life  

Stiff glass fibre reinforced cheeks to prevent lines from wedging  

Innovative design with tool-free sliding swivel locking mechanism

Applications: Plain bearing blocks are typically used for heavy and static loads in: Halyard tuning.  Mainsheet systems.  Mast foot blocks.  Mast head blocks.  Boom vang. Practical switch from swivelling to fixed shackle.
