Lewmar Control Blocks

Lewmar Control Blocks
Lewmar's high-performance Control Blocks are extremely lightweight and have unprecedented load bearing capacity. The weight advantage comes from a combination of MRT (Metal Replacement Technology) and stainless steel central race and balls. Long Fiber Technology provides you with exceptional strength and durability.
