Hi there! We have Mastic tilt windows (most seem to be from 1996). We have figured out that we have 5/8 spiral balances in our windows but are unsure of what shoes we need. All shoes in our windows seem to have a red piece of plastic in them and a piece of metal on the top.

Thanks for contacting SWISCO. I can't be certain what pivot shoe you need without seeing the pivot shoe removed from the window. Could you take a picture of it removed, and also could you provide the width and thickness of the shoe? We should be able to narrow down what you need then. Thanks.

Hi Bob,

We will try to remove one of the shoes tonight. In the meantime, here is a picture of a replacement shoe that is in one of the windows. Maybe that will help? The dimensions of the shoes are: 1 1/2 width, 2 1/8 height, 5/8 deep. Will follow up with shoe out of window. Thanks for your help! Was really relieved when we found your site. I was scared we'd have to buy all new windows!

Thanks for these! Based on these photos, give our 15-015 a look. Confirm the size and see if it's a promising match. Also, if you need help removing your pivot shoes, check out the video below.
