Photo of my coil balance parts

Question

I have a 17 lb window, measures 38" x 24.5". I need 2 coil balances. Your 152 Coil balance looks like it may be the right fit, but I am unsure. Mine measures 1/2" wide. Here is the image I took.

From the information you've given us, it looks like you have the S152-7 seven pound springs. Can you double-check and see if there is an umber printed on the spring?
