LEWMAR

Single Synchro Cruising Block - Black

50mm

Lewmar Synchro Blocks are engineered for speed, efficiency and superior handling. Lewmar uses a combination of scientifically optimized block geometry, a Free-Spin bearing, and a self-aligning head to reduce friction and increase efficiency up to 40% over conventional mainsheet systems. Each component is perfectly synchronized with the movement of the rope, providing an easier, smoother transfer of power from deck to sail and less wear on your rope.

  • Stainless steel straps and glass-fibre-reinforced cheeks
  • Unique free-spin, self-lubricating bearing
  • Easy to use, patented shackle post lock
  • Swivel lock self-aligning head
  • Optimized sheave-to-rope ratio


Note: The Mfg No. followed by "BK" denotes a block with black cheeks.
