I'm looking for truth entry guard dual arm operator. I saw a few on your site, but can't tell if they're the right size. The mechanism as a B on it and the part underneath as the numbers 31512 (both are visible in picture). The picture is of the operator on the window I can open?the one I need to replace won't open easily so I didn't want to mess with it?so I'm looking for the operator that opens the opposite direction of the one in the picture.
Can you help me find the right one?
Thank you!
