what option to get with channel balance

Question

I need channel balances for this window. It was like that when we got here. It measures 26" long x 36 "wide.
I would also like to get the weather-seal for the sides if it is possible.
I guess it weighs about 10lbs.
I would appreciate your help.
thanks,

-Peter

Hey, Peter. If your old balance does not have a stamp to use as reference, you will need to weigh your sash on a scale to determine the best match. We have a chart on the S370-25 store page that tells you how much weight each option can support.

As for the weatherseal, it looks like a type of wool pile. What specific type you need depends on the size. I recommend that you remove a sample and carefully measure the width of its base and the height of the pile, then refer to our wool pile section to find the best match.
