Description
Harken Bronze Plain-Top Radial Winches:
Harken Radial Line winches have successfully balanced the need for a secure grip and line longevity with smooth, controlled easing while under load. Details sailors will appreciate: smaller winches that carry higher loads, stress-free seasonal maintenance, and one-person installation with easy upgrades to power.
Patented angle of ribs drives line wraps down when easing to keep them on area of drum that provides best control. High-strength composite roller bearings and bushings reduce friction under load. Load-carrying gears and pins are 17-4 PH stainless steel for strength, corrosion resistance.
Maximum holding power with minimum line wear
Nonabrasive diagonal ribs on gripping surface hold line securely and reduce line wear; ribs shaped for each winch size and drum material. Patented angle of ribs drives line wraps down when easing to keep them on area of drum that provides best control.
High-strength, lightweight
High-strength composite roller bearings and bushings reduce friction under load. Load-carrying gears and pins are 17-4 PH stainless steel for strength, corrosion resistance.
Simple to install
Patented mounting system for fast, one-person installation without removing drum.
