Need to locate 4 balances.

I am looking for 4 window balances. I believe the windows may be Viking aluminum, double pane windows. The stamp on the balance is 2290 BSI 30 and they are 23 inches in length if I measure the metal part without the clips.

Sincerely,

Jason

Thanks for posting, Jason. Take a look at our S390-23, I believe this to be a match for your balance.
