Lewmar 29101110BK DC1 Single Rope Clutch Black 8-10mm (5/16"-3/8")

The Lewmar DC1 Single Rope Clutch (29101110BK) is a premium marine line management solution designed for sailboats and performance vessels requiring reliable, low-load rope control. Rated for a safe working load of up to 500kg (1,102 lbs), the DC1 series handles line sizes from 8mm to 10mm (5/16" to 3/8"), making it ideal for halyards, sheets, and control lines in this size range.

What sets the Lewmar DC1 apart is its innovative Domino Cluster technology — a non-cam clutch mechanism that uses a series of smooth, in-line, parallel rings hinged at the base. Rather than jamming the rope with teeth like traditional clutches, the Domino Cluster flexes the line, delivering superior grip with significantly less rope wear and fraying.

Key Features:

• Domino Cluster technology — flexes line for better grip and reduced rope wear vs. traditional cam clutches
• Controlled Release — pull-back handle with patented clutch and release mechanism allows smooth, controlled easing even at full holding load
• Solid link from handle to Domino Cluster for direct, responsive feel
• Line size: 8–10mm (5/16"–3/8")
• Working Working Load (WWL): Up to 500kg (1,102 lbs) — DC1 low-load series
• Single clutch configuration — black finish
• Easy installation with stainless steel fastening hardware
• High-performance design independently tested and award-winning

For best performance, select a clutch size whose upper rope range closely matches the line you intend to belay — this ensures maximum Domino deflection and holding power. The Lewmar 29101110BK is the single-channel version; double and triple configurations are also available for multi-line applications.
