Window Blancer

A contractor from Las Vegas says:
can someone please help me ID the window balancer that I have in my pictures. The width is 9/16" and the length is 35-1/16".

It also has stamped B.S.I. 33 4 on the top.

Thank you,
Alex K.

Hello, Alex. We can help you replace this balance, but it will need to be custom made. Your pictures are a great help, and we have all the information we need except one detail: there should be a metal clip at the end of the cord. If we can see that, we will send you a custom order link and price quote. I would also need to know how many you need.
