S385-29 seems to be the part I need. However I'm not sure of the stamp option. The metal channel has a 28B stamped on the side. The window it goes to is a single pane, 29X33" window. Any suggestions?
Thanks, Scott

Hi Scott,
Typically 28B translates to 2820 stamp option. A pair of S385-29 with stamp 2820 will carry a window sash weight range of 12 to 16 lbs.
Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
