The shelf will hook into the rails on the back of the freezer. The pull out shelf itself has 2 rails that attach to the shelf and then the wire part will slide into that.

Hi Ed; I understand the metal piece hooking into the back of the freezer and I see the rails on the pull out shelf that I assume slids into the metal piece, but I can’t figure out how. Any thoughts?
