I'm about to get my GE 7.2 cu ft freezer and at some point I will probably make a collar for it. I've seen some pictures but one thing I'm not clear on is how do you connect the collar to the freezer? Seems like most people use the hinges to connect the lid to the collar, but I don't see what connects the collar to the fridge. If you don't, I would guess the entire collar would tip over when the lid is opened.
