The 18" (1720) balance I need appears to have 15-005 bottom sach and 19-037 top sash. I am a contractor and need to change them for 14 windows (total needed 28). do you have any fully assembled I can order?
Thanks, Nick

Hey, Nick. I would be happy to custom make these for you. I will send you a custom order form and price quote for 28 of these shortly.
