DC1 Double Rope Clutch - 6-8mm (1/4" - 5/16") Line

Lewmar DC1 Double Rope Clutch - 6-8mm (1/4" - 5/16") Line

Lewmar continues to define rope clutch technology with a variable geometry handle and a unique grip pattern of dominoes that prevent rope fray. Unlike anything else on the market, Lewmar's non-cam clutch features a series of smooth, in-line and parallel rings hinged at the base. The line is run through these rings, which are then tilted by a single connecting lever. When tilted, the rings force the line to snake through them, creating the friction needed to hold the line securely. When the rings are allowed to resume their original configuration — that is, when the clutch is released — the line straightens and can be eased without alarm if released gradually.

This revolutionary system has been independently tested time and again and has won awards for its innovative framework. Throughout the history of rope clutch development, the cam was given teeth, which has always been a primary cause of line abrasion. Lewmar's clutch takes an entirely different approach: rather than jamming the line, the Domino mechanism flexes it for better grip and significantly less wear.

When selecting a clutch, it is best to choose the size whose upper rope range is closest to the diameter of the line to be belayed. Doing so ensures maximum deflection as the Domino flexes the line. The DC1 is Lewmar's low-load model; the DC2 is available for high-load applications.

Key Features

• Domino Cluster technology distributes load evenly across the rope, reducing wear and increasing durability
• Greater holding surface area grips the line under load without fraying
• Controlled release via pull-back handle combined with patented clutch-and-release mechanism — provides controlled release even at full holding load
• Solid link from handle to Domino Cluster for positive, direct actuation
• Double configuration manages two control lines simultaneously
• Compact stainless steel fairleads reduce friction at line entry and exit
• Compatible with line sizes from 6 mm (1/4") to 8 mm (5/16")
• Minimum holding load of 300 kg (661 lbs) per line; WLL 500 kg (1,100 lbs)
• Suitable for small keelboats, performance yachts, and sailboats of all sizes
• Manufactured in the United Kingdom
