My townhome was built in 1986. Windows are original. "Most" of my top sash guides are broken (or are about to break). My channel balance are all okay. Attached are pics of my chnnel balance in hopes that you could identify what top sash guide is needed to fix my windows.
The number marked on the channel balance is 283088081D. It is a 29" long and .5" wide.
Thanks!
Scott
