Window Balance Identification

Question

Hi,
Hope you guys can help me identifying the window balances I need. I need 3 sets of them for single hung non tilt windows. No manufacturer name on windows at all. Pics are attached.

Overall length 24-13/16.
Width 7\16
Depth 7\16
Markings: 23B (on one set) and 8 23BZ (on the other set)

Thank you,
Michael

Hey, Michael. Can you confirm the thickness of the balance? I think it should be more like 3/8". If so, I recommend our S800-24 channel balance. Look it over and let me know what you think.
