Lewmar Synchro Block

Lewmar's Synchro Blocks are engineered for speed, efficiency and superior handling. We use a combination of scientifically optimized 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 synchronized 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.

Features

Stainless steel strap for improved strength and longer service life

Stiff glass fiber 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 swiveling to fixed shackle
