Tilt window balance stamped 28 9 BSI VC

Question

My window balance channel popped out the other day, and I remove the balance and found some plastic part is old, and the thing cannot hold itself together, some rivet popped out also.

on the body of the balance, it has stamped 28 9 BSI VS, you can find it from the picture. and it uses a T-lock pivot shoe at the end, connect to the window.

If anyone can help me identify the part of the balance channel, I would really appreciate it.

Hi there!

This looks like a match to our Series 795 with a 15-195B open cam which is sold separately. Our balances install using a screw, not a hook. If your balance does use a hook to install, please let us know. You'll also need to remove and weigh your sash to choose the appropriate stamp option. There's a chart on the S795's product page that shows you which option you'll need based on the weight of your sash.
