Marineland 300DD Stand

[pyton]

Does anyone have a Marineland 300DD Stand that could tell me the size of the openings on the ends (36" side)?

I don't have a marineland stand but I have the 300DD tank and I can tell you that the frame of the aquarium is 36 x 72". So just make sure the stand allows for a slightly larger footprint.
