We have a 26-year-old patio door that badly needs replacing. For some
odd reason, the rough opening appears to be 6' 6" (6 1/2') wide. It
seems virtually all patio doors come in only a 6' width.

I checked at Menards, and they can special/custom order a few different
brands, but the upcharge is something like $400. All that for a lousy 6"
of width.

What is the rough opening for a 6' door? I've never heard of a 6 1/2', but
that does not meat they did not exist.
