Nice! I recently got some 4ft fluorescent vaportight housings from a camp I went to this weekend (I took one cover and two top housings, since the housings didn't have all of their latches so I condensed them to make one full unit). so i took them home and scrubbed them clean and then I go to put the cover on and find out that the cover is about 2" longer than the upper housing! Apparently I didn't grab a matching pair. These were just the housings though. The fixtures which mount inside the housings were already taken out and scrapped.
