Aquarium suction cups for moving large aquarium

[Dirka6363]

Does anyone have large glass suction cups that I could borrow or rent?  I am looking at ordering a waterbox 220.6, but getting it into the basement is going to be somewhat precarious.  If it were just straight through the door on the main floor I would manhandle it in with some neighbors, but there are spots at the top and bottom of the basement stairs that will be a bit tricky (6 ft tank, 4’ of space).

I believe there is a set that can be borrowed via premium membership floating around.
