Three broken tilt window balances

Question

I have three broken tilt window balances for my 30 year old vinyl windows. Even the shoe is broken on two of them. The length is 36 inches. They are 1/2 inch wide and 1/2 inch deep. I think the stamped marking says 3600 BSI.

It appears that the pieces that attach to both ends of the springs broke and when they let go two of the shoes broke into pieces also.

Thanks

Steve

Hi there, Steve.

This balance looks like our Series 775 to me. Take a look at the specifications and see if you agree. You'll just have to weigh the window sash on a scale in order to choose the accordant stamp option. Let me know if you have any questions!
