I need two of these operators - one left handed and the other right handed.
the arm length is 6", the distance between screws is 3". No visible signs of brand name. This is the garden window in the house built in 1949

Hello Emily! Appreciate your reply! Unfortunately, in the renovation mess, I can't find the casement operator :(( is there any chance to find something similar that fits? No need to replicate this hardware, we just need the opener that can operate with this window - we can also cut the window to fit the size you have or do the opposite if your operator is smaller. thank you!

Unfortunately, we can't determine what would work without seeing the entire operator uninstalled, confirming the arm length, and installation hole spacing. You're welcome to look through our selection here. We carry a few front-mounted operators you could consider, but I can't guarantee they would work based on the information provided.

Hello! I was able to find and take a photo of the arm tip - will this be helpful? Thank you!

Yes, this is a great help! Thank you for getting that for us. I recommend having a look at the 39-414 vent operator. The arm is 6" long when measured as shown below. The installation hole centers is 2-15/16". Review the specifications and see what you think.
