Need to replace these

A quick learner from Denton, TX says:
We are using casement windows that came out of a warehouse years ago. Bought them from a architectural salvage company in Dallas. Let me know if you have replacement parts. I can also send pictures of the windows themselves if needed. Thanks!

I'm not the one doing the work. Have a couple of guys doing the clean up and repair for me.

Hmm...Let's have you start with taking a closer look at both our 39-001 and 39-002 window crank operators. Carefully review the specifications of each part and see if these will work.
