Harken Radial 1 Speed Alum Self-Tailing Winch - 20STA

Brand: Harken
Part Number: 20STA
$645.95

Aluminum Radial winches are designed for sailors who want lightweight, extremely strong winches with plenty of power.

The drum’s gripping surface is shaped for each winch size and drum material and features diagonal ribs (rather than textured abrasive materials) to maximize gripping power and greatly reduce line wear. When easing, the angle of the ribs stops line from rising, preventing overrides and providing a smooth controlled release as the line exits the winch. High-strength composite self-tailing jaws and skirt save weight. Composite roller bearings reduce friction under load and don’t require lubrication. Load-carrying gears and pins are 17-4PH stainless steel for strength and durability.
