Hi! I have a Guardian storm door that was given to me due to my old one was broken and unfixable.
Everything is good except the handle and lock mechanism.
so my research led here!
I measured the components and the 40-222
seems correct. Before I order I just want to make sure.

Hello there. Without photos we can't corroborate, but if all the dimensions of your old lockset match what we show below, then the 40-222 Lockset does seem correct. Let us know if you have further issues, or if there any differences. Send us pictures and we'd be happy to help.
