Lewmar Synchro Blocks

Engineered for speed, efficiency and superior handling, the Lewmar Synchro Block features scientifically optimised block geometry, a Free-Spin bearing and self-aligning head to reduce friction and increase efficiency by up to 40% on mainsheet systems.


  • 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

Lewmar continues to define rope clutch technology with a variable geometry handle and unique grip pattern of dominoes that prevent rope fray. Unlike anything else on the market, Lewmar’s non-cam clutch has a series of smooth, in-line and parallel rings hinged at the base. The line is run through these rings which are then tilted by a single connecting lever. When tilted, the rings force the line to snake through them, creating the necessary friction to hold the line securely. When they are allowed to resume their former configuration (the clutch is released), the line straightens and can be eased without alarm if released gradually.

This revolutionary new system has been independently tested time and again and has won awards for its innovative framework.

Throughout the history of rope clutch development, the cam was given teeth. This has always been a primary cause of line abrasion. Lewmar’s clutch is an innovative approach to the line holding function. Shown in the image above right, rather than jamming the line (top), Lewmar’s Domino mechanism flexes it (bottom) for better grip and less wear.

When selecting a clutch, it is best to select the size with an upper rope range close to the size of the line to be belayed. Doing so will ensure maximum deflection as the Domino flexes the line.


  • Domino Cluster and greater holding surface area holds line under load without fraying
  • Controlled Release – Pull back handle combined with patented clutch and release mechanism provides controlled release even at full holding load.
  • Solid link from handle to Domino Cluster
  • Line size capability from 6mm (1/4 inch) to 14mm (9/16 inch)
  • Lewmar makes two models the DC1 (low load) and DC2 (high load).
