window pivot shoes

Hello, thank you for posting,

We recommend reviewing the 15-192 Certainteed pivot shoe that is compatible with the Series 170 coil springs. Please note that we have had some customers that had to shave down the aligners on the front of the pivot shoe to fit in the window channel.
