Barton DO 550 Rope Clutch 12mm

Barton DO 550 Rope Clutch 12mm (Part 81500) is a single-line rope clutch designed for cruising and racing yachts. It secures halyards and control lines with a rated holding power up to 550 kg while accepting rope up to 12 mm in diameter.

When your crew needs reliable line control under load, this clutch provides a secure, releasable hold and smooth operation so you can trim or lock lines without extra manpower. It solves common deck-control problems such as slippage, corrosion, and excessive weight.

• Holding power up to 550 kg for heavy loads
• Accepts up to 12 mm diameter rope
• Moulded high-grade plastics for lightweight impact resistance
• Anodised marine-grade aluminium cams and base for corrosion resistance
• Single DO 550 design suited for cruising and racing line control

Compared to older steel-bodied or generic clutches, this unit reduces weight while maintaining strength and impact resistance. Use the clutch on halyards, reefing lines, or control sheets where you need controlled locking and quick release.

Materials and finishes are specified for the marine environment; cams and bases are anodised aluminium and moulded parts are marine-grade plastics for long life. The manufacturer part number 81500 and Barton Marine branding make specification and replacement straightforward.
