4. 1/2 inch width

Hey there!
Thanks for reaching out to us. This looks like it could be the Series 351 or Series 390 channel balances depending on the depth of the bottom shoe. Your length is odd, though. It should measure 22" based on your stamp. Can you double-check that for us?

I believe it is 1 1/8

If the metal channel measures 22", you'd want the S390-22. The old 21D stamp may translate to our 2140 stamp option. A pair of balances with this stamp will support a sash weighing 15 to 23 pounds but you can always weigh the window sash to confirm.
