Am not sure what to order. My balance is stamped 2790 BSI vertically and then a small DE and a large 32 . Please advise . I need 4 of them.

I'm not sure about this one. My first thought is our Series 390 channel balance, but your shoe looks like it might be larger than usual. Our Series 390 comes with the 15-001. Carefully look over our measurements for this shoe and let me know if they match up.

I sent you a response last week that I thought your assessment was correct and that my balances were 28" long and 1/2 ' wide . I need 4 of them and would like a price quote.

Great, glad to hear it's a match. All pricing can be found on each product's store page, which is also where you can place your order. I would also recommend weighing your sash on a scale to determine the proper stamp option.
