Greetings, and thanks for the photos with dimensions. Take a look at our 39-378 operator that was used on ABC windows. It has the same 1-1/4" lower mounting spacing as yours, but the link arm is a little longer at 2-7/16". This shouldn't cause any issues, as this type of operator has some travel play in the linkage that should make up the difference. Hope this helps! |
