Thanks for posting. Unfortunately I can't really say what you need exactly based off this information alone, as the size of the window doesn't really tell us what balances you need. Judging from your description you may have a coil balance system, and CertainTeed windows typically use our 15-192 shoe, which uses the Series 170 and Series 171 Coil Balances. See the videos below for more information on this coil balance system, as well as how to remove your balances from the window. Let me know if you have any other questions. If this is not what you have, we will need photos of your existing hardware out of the window.
