Window pivot shoe
Hello,
Unforutnately, we are not able to make out accurate dimensions from photos. With that being said, I'd recommend starting by comparing the specifications of the 15-212 to an intact pivot shoe from one of your windows. The width and thickness are especially important. Take a look and get back to us with your dimensions written out if you notice any discrepancies. Thank you!
Height 1 inch 3/4
Width 15/16
Depth 3/8

The overall height would be a bit different since your pivot shoe is broken. Ultimately, the width and thickness are the critical measurements. Since yours matches the 15-212, that would be our best replacement option. If you decide to give it a try and run into any issues, our return policy can be found here.
