A home owner from Chicago says:

I am looking to order new window balances and want to make sure I select the right one. The numbers/letters I see on my old one are 2740, EH, B.S.I.

Hey, Tony. You balance looks like our S385-28. I would also recommend our 2740 option, of course. See what you think.
