Lewmar 40mm Control Blocks

The Lewmar 40mm Control Blocks are ideally for use with hand-held loads. They 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.

Product Features:

  • Impact Resistant
  • Reduced Friction
  • Optimised for hand control
