This operator (I need at least 4) is for a window that is 23 high x 46 wide. Can you help determine what brand it is?
If I remove one is it possible another brand would fit?

Thanks for writing in! I believe this awning operator may be a Truth brand part. I'm fairly confident we have the replacement for it. Although, to determine the correct match, I will need to see the end of the operator arms.

I'll also need to see the hardware they attach to on the bottom of the swinging window sash.

Please don't hesitate to reach out with any additional questions you might have!

Hi Greg,

Thanks for the additional photos. You'll need either the 39-312 or the 39-454 to replace your operator. To determine which of these is the correct replacement, carefully compare the specifications below; they each have the same installation hole pattern.

They are front mount operators so you'll also need the 33-205 SS #10-24 Thread Nut for the installation. To insert them, you'll need to use a vise. This will allow you to install it as a rear mounted operator.

Both operators are compatible with the 39-114L and 39-205 (this one is folding) crank handles.
