35 inch window balances

Thanks for posting. See either our S380-35 or S385-35. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. 

You will then need to select a stamp option. Your stamp code of 34 9 is from an older rating system we no longer use. To know what stamp option you need, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the product page.
