Thanks for posting! Based on your photos, I recommend our S395-29 channel balance. This comes with a 19-005 top and 15-001 bottom, so as long as those match you should be okay. What's more is that these were used in many Atrium windows, so I think this is your best option. As for installation, see the video below. This should cover everything. If you need help, let me know! |
