Jeff that is the full size of the HA glass. On each side there are two pieces. First out from lamp are the two pieces of HA glass (forming a square) then the filter is one piece. Why the HA glass is in two pieces I have no idea. The metal frame that holds them is split in the middle and held together with two bolts. The lamp/filter assembly is held onto the back bracket by two bolts as well. They are screwed into bracket - there is no nut on the back to come loose, but there might be some washers and depending on the setup square tube which acts as a standoff.

Mine on the other hand is truly broken, and one side missing completely.
