Casement window crank

Thanks for writing in to us! Your casement window operator looks a lot like our 39-400 Roto Single Arm Operator; the opposite handed version is the 39-399. To confirm that this is the correct replacement, carefully look over the dimensions and compare them.

You should be able to reuse your existing track slider; however, this operator is compatible with the 39-541 Roto Casement Track Slider. You also likely need the 39-232 Roto Folding Crank Handle.
