Synchro Double Block with Becket

Designed for speed, efficiency, and exceptional handling, Lewmar’s Synchro Blocks combine advanced engineering with practical innovation. Featuring scientifically optimised geometry, a free-spinning bearing, and a self-aligning head, these blocks reduce friction and deliver up to 40% greater efficiency compared to standard budget blocks in mainsheet systems. Every component works in harmony with the rope’s movement, ensuring smoother power transfer from deck to sail and significantly reducing rope wear.

• Versatile Head Design – Can be set in-line or at a 90° angle, or left to rotate freely when unlocked. When locked, it allows a 30° “float” on the shackle post for improved block alignment.
• Stainless Steel Strap – Enhances strength and extends service life.
• Glass Fibre Reinforced Cheeks – Rigid construction prevents lines from jamming.
• Tool-Free Swivel Locking Mechanism – Innovative sliding design for quick and easy adjustment.

Plain bearing blocks are ideal for managing heavy or static loads in applications such as:

• Halyard tuning
• Mainsheet systems
• Mast foot blocks
• Mast head blocks
• Boom vangs
