Product Description
Harken #40 Radial Self Tailing Aluminum Two-Speed Winch
The Radial winch 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. The self-tailing mechanism on the winch means that one crew member can quickly and easily trim or raise sails.
1. Roller Bearings Snap-fit design keeps bearings captive in a high-strength Delrin cage when drum is removed for maintenance.
Composite roller bearings don't require lubrication.
2. Gripping surface Each winch size has its own radial grip shape to optimize holding power and for smooth, controlled easing.
