I need to replace some channel balances on some Milgard nontilting windows. Channel is 1/2 inch wide and 30 inches in length.

Hi there!

Based on what I see here, I recommend you take a look at our S380-30 or S385-30 channel balance. Each of these Series has a different sized bottom fitting so you will need to measure as shown in the image below. Our Series 380 has a 1" deep bottom fitting and our Series 385 has a 1-3/32" deep bottom fitting. For a spring strength, you will need the 2930 option.
