Hi, Ren. Based on the length and other info you provided, you would need S350-21 with a stamp of "2020." It's odd for the new stamp, 2020, to be so different than the old stamp, 21B, though. Can you verify that the metal channel measures 21" by itself? You may also want to check the weight of your window sash and send it to me.
