Thanks for posting. This might be an S351-28 Channel Balance. Compare the specifications listed to your old balance to confirm. You'll then have to choose a stamp option. Your balance's old stamp of 2790 is from a rating system we do not use. To know what stamp to select, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp on the balance shop page.
