Lewmar 29927221BK Synchro 72mm Halyard Block

Lewmar's 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 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.

  • Stainless steel strap for improved strength and longer service life
  • Stiff glass fibre reinforced cheeks to prevent lines from wedging
Applications: Plain bearing blocks are typically used for heavy and static loads;
  • Halyard tuning
  • Mainsheet systems
  • Mast foot blocks
  • Masthead blocks
  • Boom vang
The toggle heads of the halyard blocks are designed to fit on the studs commonly found at mast bases.

Consult the Catalogue page below and check the stud's diameter against the block jaws' width and pin diameter.
