This looks like the set I have in my Atrium wood door. How do I know that it's an exact match? Did Atrium only make one set for it's wood doors or are there several?
I believe the Swisco 82-400 was used on the original (older) Atrium doors. The design may have changed since then. If you cannot locate the needed hardware on our site, you can submit photos of your lock (with dimensions) for us to research.
