Also, I know it sounds kind of sounds like a cheap way to rig something up, but on the bottom set of grills use these.



You can find them at Wal-Mart, or some office place.
Pretty much wherever you go will probably have them. They're called binder clips, or office clamps. Some people call them different things.

Trust me, I, and quite a few others with these grills, and even the more expensive SS grills use this setup. Zip tie the upper ones on, clamp the bottom ones.
