Harken offers a wide range of low-friction ball bearing winch handles. These ball bearings offer an efficient transmittion of power into the winch and will fit all standard winch sockets. Locking vs. Plain Lock-in Handles are easy to engage and release with a thumb switch. Plain handles are faster to insert. 203 mm (8 in) handles grind faster because they swing through a smaller circle, but power is reduced by 20%. 8 in (203 mm) handles are ideal for smaller boats and light air where speed is more important than power.
