Lewmar 29925001BK 50mm Single Synchro Sailboat Block
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.
Note: The Mfg No. followed by "BK" denotes a block with black cheeks.
