Truth 40056

Hi there! 

I don't recognize this operator with your specific arm measurement at first glance but I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available.

Thank you! 

I don't believe Truth still makes that 11-1/2" arm. We carry these operators with the newer style body, but we only have the 39-028E with a 9-1/2" arm and 39-014 with a 13-1/2" arm. I'm not sure if you can use an arm as long as 13-1/2" so you might have to settle for the 39-028E with a 9-1/2" arm.

Take a look at the operators we've associated for you and see which one would fit your window best. I also suggest replacing the track and handle, we've associated parts for that as well.
