HANDLE 200mm LOCK-IN A/A Ball bearing handles. Lewmar ball-bearing handles were originally designed for and tested by the top America's Cup crews. So popular were these handles that we are now making them available to cruising and racing sailors everywhere. These Lewmar handles use twin ball races to provide a 'feel' and an effortlessness no ordinary handle can match. Remember that Lewmar's ball bearing handles will fit any international standard winch socket...even those on non Lewmar winches! Lewmar's ball bearing handles are available with a handy two way lock-in feature, which keeps the handles firmly on the winch. Releasing the handle is quick and simple... using either hand, you just push the spring loaded release to the left or right. Lewmar's ball-bearing handles are built from one of two different materials.
