Pivot shoe lock and coil holder needed

Thanks for posting. This pivot shoe looks like our 15-192, which uses our Series 170 and Series 171 Coil Balances; see the video below. However, is this by chance a Simonton window? If so, there's a chance that the metal cam in your shoe might be slightly different in configuration. If so, we recommend you swap it out with the one that comes with the new shoes, so your pivot bar compatibility isn't affected. Let me know what you think.
