More Information

Lewmar DC Clutches feature a unique domino grip technique that utilises a series of rings all connected by a single lever:

The line passes through the series of rings which tilt when the lever is compressed.

This action forces the line to snake through the rings.

When fully compressed the snake provides holding power over the full length of the rings.

The lack of any teeth combined with the spreading of the load significantly reduces line abrasion.

The lever can be released gradually to allow you to feel for the point at which the line will begin to ease. This controlled easing allows the crew to manage drops and hoists in a more stress-free way.

There are three sizes to choose from. 8-10mm, 10-12mm and 12-14mm

Important Lewmar Advisory
When choosing your clutch, be sure to match your line diameter as close as possible to the upper end of the range for maximum holding power.
e.g. for 10mm line diameter, select the 8-10mm DC clutch
