I am replacing the broken balancers in my windows. They look like the 350 series. They are 29 inches long. They have stamped on them ub 26D USB and 28D USB. I was wanting to order the correct one. Thanks Jim

Thank you for posting, and for the pictures. Are these two balances both in different windows, or are they a single pair in a single window?
