Good Afternoon, I'm in need of new balance pieces shown in the attached pictures. When I measured the piece it came out to a little bit less than 29in. When I looked up the code on the piece (2850) on the website, a completely different piece came up. Please help.

My tension rod has fallen down & I can't figure out how to get it out. The number in the picture is that the stamp identification?

The metal part is exactly 29" long, 9/16" wide, and 1/2" deep. Stamp on it os 28C USB. Photos attached.

Bottom clip is 1"" deep. Balance length is 29"

I figured that these are s380 rails 29” long. But the only stamp on them is 28C so not sure on the weight rating to pick. Aaron

Thanks for checking this out. Maybe you can help us. Look forward to hearing from you.

Need to replace both balance channels in my single pane window sash. They are stamped with a 28D and no other markings. I'm needing help determining the actual replacement for it as the single number/letter is apparently no longer used.

The original channel balances were stamped BSI-2820. We ordered a pair and they fit, but they could not hold up the sash. Sash=37 lbs. Channel length=29 in. We bought 2 different sets from 2 different places and both sets were to weak to hold up the window. Can you help? Thanks!
