My channel balance has the numbers 38 and 2990 stamped on it which I don't see on your list. It is 1/2" x 30". The window measures 50" wide and 30 1/2" tall. What balances should I order?

Thanks for posting! Before I can offer an applicable replacement for this channel balance, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?
Can you also weigh your window sash? A stamp of 2990 does not match any of our corresponding options and we will need to know the sash weight in order to recommend one.

My bottom attachment is 1" and the weight of the window is 30.5 lbs.

Great! In that case, take a look at our S380-30 channel balance with a 3950 option and let me know what you think.
