I need to replace my 23 inch series 350 channel balance. Stamp on the current balance is 22E USB. Please advise the option I should select when ordering new balance for the windows.

A stamp of 22E could corresponds to our 2250 option, but you should check the weight of your sash to make sure it matches the weight rating shown for the 2250 as listed on the S350-23 page.
