Window balance needs to be replaced

I have a sliding windows(up and down) that won't stay open once I let go. Turns out that the window balance on both sides of the window sash are broken. I took the parts off but couldn't find replacement parts anywhere.
The only numbers/letters I can identify is DB L02 30 HD.
Can you please help identify which replacement balance might work for me?
Thank you,
Rudy



Hi Rudy,
Thanks for your post! The balance you have here can be replaced with the S751-31 Channel Balance. This is a ribbed channel balance with a 15-014 Balance knife lock Shoe attached. You can select the 30HD option.
Also, be sure to double check that the clips don't need to be replaced at the top of the balance. This balance uses either the 19-029 Short or 19-030 Long S-Clip.

Thanks,



Yes, you can drill a hole in the top of the balance but you'll need to make sure it sits at the same position as your existing hole. Please be aware that altered balances cannot be returned or refunded.
Feel free to reach out with any other questions you might have!
