Harken winch handles are a blend of good looks and smooth efficiency. They are a perfect enhancement to any winch. Harken handles fit international standard handle sockets. Metal handles feature ball bearing grips for smooth, comfortable operation. A ball bearing grip ensures that your power is transmitted into the winch with the greatest efficiency, with no annoying drag. Lock-In handles are easy to insert and release with a conveniently positioned thumb switch. However, some racing crews prefer plain handles because they are easier to insert and are priced less. The 10" handles are the industry standard because they have proven to be the most comfortable length for most sailors.
