Mauri Pro Sailing Product Description Template


The Lewmar 50 mm Double Becket Synchro Block is engineered for speed, efficiency and superior handling. It uses 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.

Product Features:
  • 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
  • Simple switch to change from swivelling to fixed shackle
