truth casement window operator

I'm not sure what your question is. Are you asking if the 39-013 is the operator you need? If so, I cannot confirm, as I was unable to cross-reference those numbers. They could be old numbers that the manufacturer no longer uses.

Honestly, numbers stamped on an operator aren't often the best way to find out what you need. The best method is to compare the style and dimensions to the pictures we show on our site.
