Truth Entry Gard casement window operators

A handy person from Evansville, IN says:

I have two sets of windows in need of complete operator replacement. These pictured are both marked with R(assuming right hand window if viewing from outside), as the Left operators are still installed (I will need to replace those as well).

The long arm is marked 40754 and the short arm is marked 31538A.

Hello,

Take a look at the two sets of operators we've associated for you on this page. They are both very similar to yours but the main difference is the length of the shorter link arm on your operator. Take a look at the dimensions on our product pages to see which operators you need for your window. Thank you!
