Today’s streamlined and efficient deck layouts use purchase systems led to cam cleats for a number of functions that a decade ago would have been more likely to be led to a bank of clutches.

This product takes the concept of a cam cleat and re-engineers it to maximise holding capacity on lines of 6-10mm in diameter.

The closed aluminium structure is designed to protect the working parts from impact damage, while also providing additional strength – the safe working load is 250kg (or 310kg if the optional fairlead is fitted).

A new design for the aluminium jaws provides good grip, even at high loads, while the cams benefit from both ball bearings and a strong spring that holds them firmly against the line.

We used it for the purchase system of towable headsail sheet cars on a 36ft racer-cruiser.

The SWL ratings give ample headroom to accommodate shock loads on a line that needs to be adjusted by hand.  www.karver-systems.com www.allspars.co.uk
