40MM SC BLOCK CHEEK BK

MIA's Description

The Lewmar 40mm Control Block is a single, cheek-style block designed for use with hand-held loads in sailing applications. It features a ball bearing system for efficient operation and reduced friction, ideal for control lines, mainsails, spinnaker sheets, and genoa sheets. The block is constructed with durable materials, including a high-strength sheave and stainless steel components, and its open design facilitates easy maintenance by flushing out sand and salt.
