Harken HKW20STC Radial Winch Chrome-plated HKW20STC
The introduction of our Radial Winch line signifies a new level of performance.
Reduced wear on the line is a notable feature of the Radial Winch; its gripping surfaces are shaped to avoid dependence on friction.
Fingers and clothing are safeguarded from getting caught in moving parts, thanks to the complete coverage of the winch tops.
Seasonal maintenance becomes exceptionally easy with the top lifting out as a single unit, ensuring quick and mistake-free reassembly.
The Radials grip functions akin to a screw, driving the line downwards for enhanced control on the drum.
Composite roller bearings and bushings minimize friction under load, boasting excellent corrosion resistance and negating the need for lubrication.
This design also results in a 25 to 50 percent reduction in weight compared to conventional winches.
Why the Different Grip Pattern?
Chrome, being more slippery than Aluminium, necessitates closer spacing of ribs on chrome Radial winches to increase friction.
This optimization enhances grip for both trimming and easing the sail.
