My Series 795 has a hook on top, not a screw
Hello! Sorry to hear you're having trouble with our balance. I see the problem, though. This is fairly common. You need a Series 795 balance with a 15-198 hook attached at the top of the cord instead of the default screw tab. We can supply a balance with this configuration but it would have to be a custom order.
Before we go any further, I would first recommend that you return the balances you purchased for a refund. You can see our return policy here.
Next, can you tell me the size, stamp, and quantity of the balances you purchased? Once I know that, I'll duplicate those balances but will make the necessary changes to fit your window. They will come fully assembled with a 15-194 bottom shoe and 15-198 top hook.
Perfect, thank you! So, I'm going to email you a custom order link right now. That will include a price quote and will allow you to add these balances to your cart as if they were a stock item. You can then checkout as normal.
Please let me know if you had any questions.
