Block Guidelines

Control Blocks:

Ideal for use with hand-held loads, Lewmar's Control Blocks feature lightweight, performance load-bearing 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. 

Synchro Blocks:

Lewmar Synchro blocks are engineered for speed, efficiency and superior handling. We use 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.

Stainless steel strap for improved strength and longer service life ▪ Stiff glass fibre reinforced cheeks to prevent lines from wedging ▪ Simple switch to change from swivelling to fixed shackle.

Synchro Footblocks:

Synchro Footblocks feature alloy cheeks, fixing isolators, and a moulded base plate to prevent sealant ingress into the sheave. Jamming footblocks are designed to hold light hand loads only.

HTX Blocks:

Years of design and manufacturing experience, combined with collaboration with boat builders, designers, and sailors, has resulted in the Lewmar HTX Hardware Range.

▪ Strong aluminium side cheeks ▪ Central plain bearing for efficiency at high loads ▪ Side thrust Delrin ball bearings ▪ Head design inspired by Lewmar Racing Range, complete with grub screw swivel head locking mechanism.

Racing blocks:

Lewmar Racing Blocks represent the pinnacle of Lewmar's standard block range. Manufactured from the best materials, they offer incredible strength to weight ratios.
