Need advice on selecting pivot shoe in aluminum window.

Hello,
I need some advice with Pivot Shoe selection. It is 2.0" high, 1.25" wide. I measured the thickness while it was installed and it could be 17/32" or 9/16" (not sure).

See photo.

For reference, the window is 30 years old, aluminum construction. Its two Spiral Balancers are 24" long x 0.55" diam.

I think the Product Code 15-015 would be the correct pivot shoe. But in case I am wrong, do you have any other shoe selections I should add to my cart as backups?

Best Regards,
Thomas

Hey, Thomas. The 15-015 is a good start, yes, though you may want to get the exact thickness just to be 100% sure. We also have the 15-046, which is 1/2" thick, and the 15-121, which is 9/16" thick. You can also see our return policy here, just in case.
