Need new operator

I believe you'll need the 39-014 Casement Window Operator to repair your window. It is an updated version of your existing operator. To confirm that this is the correct fit, you'll need to compare the dimensions.

The compatible hardware an accessories can be found tagged below.

Dimensions for 39-014

I noticed you provided the dimensions for the arm on the casement window hinges at the top and bottom of the window. These are sold separately from the operator but I'm happy to recommend a replacement for them, if needed. I'll just need to know the length of the track installed to the window sill.
