ABSTRACT:
The crank handle of a window sill used for actuating a window pane has a hollow end in which is received an insert allowing the handle to engage various sizes of crank shafts. The insert is formed of a malleable material so that it can be deformed to fit the diameter of a crank shaft to thereby securely engage the crank shaft and enable its rotation by the handle.
