Hi there!
Thanks for reaching out to us. We should be able to help with this. Can you write out the diameter of the outer tube for this balance?
I'm happy to help! In this case, I recommend the Series 500 as well as the 17-012 bracket which is sold separately. Take a look at the specifications and see what you think.
To determine the length for your replacements, add 3" to the visible glass height on the bottom sash, and 1" to the visible glass height for the top sash (if relevant). For example, if the visible glass is 15" high, then you want an 18" long balance (bottom sash) and 16" long balance (top sash).
I'm happy to hear that you were able to determine the balance lengths that you need. Unforutnately, we are not able to process orders through this thread but you can purchase the S500-29, S500-27, 17-012 brackets, and 75-005 charging tool directly on our website. You are also welcome to give our customer service team a call at (888) 991-1929 to order over the phone.
