Channel balances

Question

these are two parts to my channel balances. They are 9/16 and about 29" long. There's a stamp on the side that says "28 9"

I can't find parts that match this on any website. Any help is appreciated. Thank you.

Please see our Series 795 channel balance, this may be a match for what you need. I would recommend weighing your sash to confirm the best possible option, since "28 9" is not a typical stamp, at least not under the system our balances use.
