Keller Window Operator

Hello,

I have a 1950s house with Keller awning windows. I am in need of replacement operators.

The measurements are 5-1/4" top screw to bottom screw with a 2-3/4" arm extension.

This is the old one and I saw somewhere on your site that the screw hole size in the link arm is important. I believe this one is 3/16" and it has a little plastic bushing as well.

Any help would be appreciated.

Many thanks,
Philip

Hi, Philip.

We appreciate you reaching out to us. Your operator's link arm is pretty odd and I'm not sure we have anything that may replace it. I'd be happy to look into this though. To help with my search, can you show us a clear photo of the installation hole pattern? I can't see how yours are configured from this photo and that's a very important detail that will allow me to narrow down some options.

Thank you!

Hello and thanks for the reply. Please find attached a photo of the screw hole configuration. I've also supplied a schematic of the crank I cannot locate but I believe is the correct one.
If I have to drill out a new screw hole pattern I can but I'd prefer to find something that just fits and works.

Hey there, thanks for getting back to us. Emily isn't here today but I'll try to help you out.

Like she already mentioned, we don't sell this exact assembly. We do however carry the 39-061 awning window operator, which was used by Air Control and Keller. The link arm is a little shorter than the 2-3/4" yours has, but there is some travel in the linkage to make up the difference. In my experience that particular dimension doesn't have to be exact.

In your drawing it also shows an off set gear arm. Not sure you would need that. I have used the 39-061 operator in the past to repair Keller windows and they worked fine. That's not necessarily a guarantee, since these are old windows, but it's been my personal experience. Take a look at the 39-061 along with the related hardware and video to see if the operator and parts match up to what you need.
