Thank you kindly! Your balances indeed look like a match for the Series 350. Your stamps are outdated though so you'll have to weigh the window sash on a scale to determine the proper stamp options. There's a chart under the product description on the S350-28 store page that will help you choose the best stamp option based on the weight of the window sash.

Let me know if you have any questions!

For the 34.6-pound sash, you can use the 2765 stamp option. A pair of S350-28 balances with this stamp will support a sash weighing 33 to 36 pounds.

For the 28.4 and 28.8 pound sashes, you can use the 2750 stamp option. A pair of S350-28 balances with this stamp will support a sash weighing 26 to 30 pounds.
