Looking for a window balancer that is stamped P 4450. Overall measurement is 45in x 5/8"x 9/16". These balancers came out of a school that has no info on the brand or model of windows. Any information would be great. Thanks

Hi there!
Thank you for reaching out to us. We're happy to help with this, but it will have to be a custom order due to the length. Can you confirm the length of just the metal channel? We'll also need you to weigh the window sash and get back to us with the precise weight so we can confirm the correct strength calibration. Additionally, how many balances are you looking to order?
Custom orders are nonrefundable, so you're welcome to upload photos of the balances to ensure we're getting you the correct parts for the repair.
