Thank you for your help in advance. I have some single hungnon-tilt windows with Channel Balances that are shooting up to the top of the track and some that fall down to the bottom of the track.
Can you help me understand what the different causes for the channel balances being either at the top or bottom are instead of in place with sash?
I have some pictures of the 1420 with BSI and ND inscribed. I also have some 3240 BSI ND balances that need attention, but I haven't had time to take pictures.
Thank you for your help!
