Lewmar 60 mm Synchro Double Block - Swivel, 2992-6002

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 swivel lock 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.

Note: Special Order Only

• 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

Plain bearing blocks are typically used for heavy and static loads in:

• Halyard tuning
• Mainsheet systems
