Inverted block and tackle window balance

Question

Hello! I'm looking to replace some busted window balances. The stamp in the photo reads "26 7 BSI RG" as far as I can tell. The balance from the other side is stamped "26-5 RE" and is otherwise the same in measurement and appearance. Both are 27" long and 1/2" wide. The window sash weighs 25lbs. Have you the parts that would replace these?

If the metal channel, not including the bottom T-Lock Shoe, is 27" long, then you need our S795-27. For a new stamp option, choose 27D, which will support a window sash in the weight range of 22 through 26 pounds. You will also need to purchase our 15-195B Open Cam shoes, sold separately. The video below shows how to easily swap out these shoes with the ones that come attached to these balances by default (our 15-195). See below.
