Lewmar D1-1/4-5/16 Single Clutch: Setting the standard in rope clutch technology, this product features a unique variable geometry handle and a special grip pattern that minimizes rope fray. The innovative non-cam clutch utilizes a series of smooth, in-line rings, tilted by a single lever, to create necessary friction and securely hold the line. This design avoids line abrasion, commonly seen in traditional cam clutches. Independently tested and award-winning, this Lewmar clutch offers enhanced grip and less wear through its Domino mechanism. For optimal performance, choose a clutch size with an upper rope range close to your line size to maximize deflection.
