I need Nu-prime replacement sash balances. There are no balances in the window for me to use as a guide! I need 4 balances for a sash where the visible glass is 28" wide x 14" High, 2 balances for a sash with visible glass 26" wide x 15 1/4" high and 2 balances for a sash that is 26" wide x 13 3/4" high. Can you help?

Most Nu-prime windows use our Series 390 channel balance. Of course, there is no guarantee that this is what you have, but it's a good place to start at the very least.

Based on your glass sizes, I would recommend our S390-15 with a 1420 stamp for the first sash, S390-16 with a 1520 stamp for the second sash, and an S390-15 with a 1520 for the third sash.
