I always viewed the UA2 as an odd design and a bit of a beast. We replicated it's dimensions as a 1-piece design for simplicity for this one guy, but thankfully we asked him to check the dimensions of where it was intended to go first, and he discovered it wouldn't fit in his garden office door. We took the size in ( but kept it as large as possible at his request) so it just fit in through the window frame.
Glad to see you had the sense to take that ---smurfette--- in a bit too.
