Patriot window channel balance

I have Patriot windows that need new channel balances but I have no idea which ones to order. The channel is 25 inches long has the number 2500 BSI LF stamped on it but I can't find the proper channel. Any help you can give will be greatly appreciated. Thanks.

Hello,
For your Patriot window, I suspect that you may be able to use the S795-25 channel balance as a replacement. Your 2500 indicates that you may require 25B strength options for a sash between 11-17 lbs.
With that being said, this is an educated guess since your balance assembly is broken and missing the t-lock shoe. I would recommend removing an undamaged balance to compare to the specifications shown on our product page, as well as weighing your sash to confirm that it falls within the supported range. If you're not sure, feel free to get back to us with more information and additional photos to look into this further. Thanks for posting.




These additional photos are very helpful. Take a look and compare the specifications of the S770-25 channel balance to your assembly, which has the same terminal clip at the end of the pulley and screw way at the top of the channel for installation.
I would still recommend weighing your window sash and following the chart under the balance product description to confirm the correct strength option for your replacements.




Great, then you would need a 25B strength option for your replacement S770-25 channel balances. Please let us know if you have any other questions.
