replacement casement window crank operators?

Question

I need to replace several 1980s-era casement window operators.  Single-arm, 11inch arm from wheel center to gear center.  Top-mount?  No vendor/model markings that I've found.  Thanks.

Thanks for writing in! We aren't able to provide you with an operator that has an 11" arm but there are two possible replacements that will work for your repairs. Take a look at the 39-013 Casement Window Operator (with a 13-1/2" arm) and the 39-027E Ellipse Style Single Arm Operator (with a 9-1/2" arm).

The window may either open slightly farther or may not open as far depending on the length you choose. Keep in mind, you may need to make adjustments to the track to accommodate for the difference in the arm length.

The compatible handles are the 39-114L Crank Handle and 39-205 Truth Folding Crank Handle.
