I got a Titan Eze double metal stand for my 75 gallon, and it looks like two of the poles have holes in one side, it almost looks like they are for bolts to secure the stand, but I can't find a use for them. Does anyone know what they are for? I have two other Titan Eze stands that I use for my 40 gallon tanks, but I can't remember what those holes are for. The stand didn't come with any instructions.
