Need help finding a 28x80 Door for our inherited cats

[toxic111]

I hate to say it, it will probably be very difficult to find an exterior door that size, as it is not very common (so rare I have not seen one in 24 years of building design)

I would say check the habitat for humanity restores, and other used building supplies. Or if you can find an antique building supply store.

I think to truly get that size it would have to be custom built, which as you know is $$.
