Part No: 81500 Categories: ,


True clutch mechanism
This true clutch mechanism allows lines to be adjusted through the unit in the closed, locked position with minimal slippage.
Release under load is positive and requires little effort.
The mechanism’s opening and closing action is precise and easy to operate, even with cold, wet hands. A positive handle lock in the closed position is also featured.

Kind to lines
The clutch’s cam and base, manufactured from high grade extruded aluminium, feature a specially tempered tooth design which allows for maximum grip with minimal slippage, whilst being kind to your lines.
Stainless steel rope fairleads are fitted to both line entry and exit points; a feature which helps to prevent wear to both clutch and lines.

Bolt-together construction for straightforward servicing
The DO 550 clutch range features the advantage of a bolt together construction which allows for ease of servicing and replacement of parts. A full range of components is available from our Barton stockist.

Important fitting notes: rope clutches
When fitting ensure a fair lead straight through the clutch to prevent wear to side plates and/or reduced
load capabilities.
For best performance site clutch approximately 1ft (300mm) forward of the winch to ensure a fair lead
both vertically and horizontally.
Use Barton deck organisers forward of the clutch to gain perfect alignment.
Always use a bolt-through fastening with a suitable sealant.
A drilling template is provided on our packaging for your convenience.

Ergonomically designed handle
The handle is strong and easy to grip, with a positive smooth lock and unlock action.
A unique feature of this new design is the removable insert on the top face of the handle.
These inserts are available packaged separately with a selection for both cruising and racing yachts.
