grill extender

I stopped by a local store to pick up a grill extender so i can cook four buts on my grill dome instead of two. I was surprised at how short the legs are on it and can;t see how it would sit on top of two buts with out resting directly on the meat. Is this how it is supposed to be? I have never used on before and am interested in the additional space it would provide. I was talking with the salesperson and they mentioned the new three tiered rack. Has anyone used on e of these yet? Any thought on it? what about the specs on spacing between the different grills?
Thanks

I will have to try that. Do you have a pick of the legs and how they are attached? I think i figured out the feet.

sorry.:icon_blush: I just saw it on your thread. I will have to try that.
