One hand to lock, one hand to unlock, that's all you need with this 10 in. Lewmar OneTouch Standard Grip winch handle. Lewmar's patented ﾓone touch in feature uses a plunger pin and ball mechanism similar to that employed by the quick release steering wheels used in Formula 1 racing. To insert, simply squeeze the release lever (which runs the entire length of the arm) and place into winch. To remove, just squeeze the release lever again and lift up. All it takes is one hand. Finally you can spend less time fiddling around and more time racing, cruising and/or beverage holding. The Alloy handle is a lightweight, forged construction and also provides corrosion resistance. 10 in winch handles can offer additional leverage when power is more important that speed and are most commonly found on keel boats about 30 in and up.
