Dear Swisco, I need to replace both balances on a plastic frame double pane glass window that weighs 13 lbs. The window frame measure 33" wide and 22&12" high The metal part of the balances are 19 & 1/2" long by & 1/2" wide and and 5/8" deep. Marking on the left balance(looking out) is 19 4 & BSI RL. Markings on the right Balance is 19 3 & BSI RL. No manufacturers name or branding on the parts or window. I have replaced balances on another window in the past with your assistance, so I'm familiar with the process. Thank you! Bill

Hello,
We can supply your replacement balances but it will need to be a custom order due to the length, extended travel pulley system and unique combination of end attachments.
The balance stamps on both sides should be the same. Since yours are different, someone most likely replaced one of them with the incorrect replacement but we can confirm the spring strength needed based on your 13-pound sash weight.
We just sent over an order link and price quote for the balances you requested. Take a look and let us know if you need anything else. Thank you!
