ABSTRACT:
A casement window low-profile operating apparatus comprises a winged hub having an aperture therein which is adapted to receive any of different size window operator crankshaft adapters. The crankshaft adapters themselves contain an aperture designed to fit the gear of a variety of window operator crankshafts. The handles may conveniently be supplied in the form of a package kit which includes a series of different size adapters, together with the hubs, allowing a correctly sized adapter to be selectively fitted to a particular window. The adapter is installed in the handle and the handle affixed to the crankshaft of the window operator where it can be operated without interfering with window accessories such as curtains, drapes, blinds and the like.
