Need to replace channel balances and top sash guides for non tilt window.

See our S351-33 or S390-33. 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. Your stamp code of 32-9 is from an older rating system we don't use. To know what stamp option to select, get the exact weight of your window sash, then match it with one of the weight ranges listed alongside each stamp option on the balance product page. 

For the Top Sash Guide, see our 18-171.
