OK, I'll try not to twist. That would make sense to have them fit that
way.

Not sure of the "official" name, but I'm referring to the wooden
framed box structure that fits around a chimney pipe coming through the
roof to give it a chimney appearance. Mine's about 3' X 5', with
siding on all four sides and trimmed out with 1X4s around the top and
corners, a heavy steel plate fitted over the top with a chimney cap on
top.

Thanks for the inputs.
