Antal’s new self-tailing winches with spring loaded self-tailing disk adapt automatically to even the thinnest lines and, if overloading occurs, they release the line to avoid excess force on the self-tailing arm. The base, machined by the CNC process (produced with no cast components, is lighter and stronger than normal castings. Easy removal of the drum from the winch makes maintenance a simple affair. Vertical knurling on the drum delivers a secure horizontal grip, but allows the rope to run vertically upward without excess friction for maximum efficiency. The self-tailing arm has 30 positions. AISI 316 stainless steel central rod and roller bearings, bronze gears, hard black anodized drum or chrome-plated bronze drum. First gear provides quick and powerful operation, and you simply wind in the opposite direction for maximum power in second gear. The recovery speed, shown in the table, is the length of line recovered with one complete revolution of the handle. Three-year warranty.
