It is a Truth casement operator that is stamped B and is attached to an Older Marvin Integrity casement window. I'm having a hard time matching up the dimensions with an available operator. Please assist. Thank you.

Thank you for your response. My only concern is that the broken part of the arm with the clip on it is 5" and the existing one is only a little over 4". Will this affect the operation of the window? Also is the shell from the operator you posted only available in white? I see the corresponding handle is available in multiple finishes.

I believe you have an old-style Wright products operator. Wright products used the same operator and used different length link arms depending on the window specifications. You might still be able to use the 39-172 operator and move the sash bracket over to compensate for the longer link arm. Another idea would be to reuse the link arm from your existing operator and attach it to the 39-172 operator using the 62-014 rivet. Please note that Truth only makes this particular operator in white, though the handles that we offer for it are available in multiple finishes. Take a look at the suggested hardware and related videos shown on this page to see what you think. Thank you.
