Lewmar 50mm Synchro Block 10mm - Single With Toggle Head

Ideal for use with hand-held loads, Lewmar’s Control Blocks feature lightweight, performance loadbearing capacity. MRT (Metal Replacement Technology) and a stainless steel central race and balls provide a weight advantage, while Long Fibre Technology offers exceptional strength and durability. The open design allows sand and salt to be flushed out easily, keeping maintenance simple.

Features:

• Lightweight
• Very High Strength
• Impact Resistant
• Reduced Friction
• Easy Maintenance
• Optimised for hand control

Applications

Ball bearing blocks are typically used for medium and dynamic loads in:

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

The toggle head of the halyard blocks is designed to fit on the studs commonly found at mast bases – check the diameter of the stud against the width of the block jaws
