On my AGA 125 the part that sits on the stand is 1" wide. The plastic piece is 1 1/4" but only 1" contacts the stand. It looks just like the top flipped over. It even has the center braces and the notches for the glass top to recess in. From what can tell the frame on my looks just like the one in your journal. I have the same stand. Can't you see the bottom when setup? There is no top on my stand. I measured this with the aquarium set up.
