top need Clip instead of screw in

Thanks for writing in. Unfortunately, replacing the screw tab with the 15-198 hook is a bit of an involved process, which is why we do them as custom orders. There may, however, be an alternative to having to return your balances. Can you show us a picture of the hole in the window track that the hook attaches to? Depending on its shape, you may be able to use our 26-200 Screw Plug, and thus use the balances you purchased. Let me know what you think
