The three horizontal jerky rack shelves come with two vertical side walls to set the racks into place. After uninstalling the bolted in brackets for your normal warming rack (which is a silly design), you just set these two walls under the main bottom grill grates and slide your jerky racks into the grooves in the walls. The problem is that the walls/brackets are too far apart and the shelves fall down on one another. The ‘grooves’ that come out of the walls to hold the jerky racks in place need to be about a half inch or so longer so the racks can actually fit in between the walls. Like another reviewer here, I had to put tin foil in the grill to push the walls closer together so the racks will stay in place. Otherwise the top rack I had to delicately place crooked on the top of the rack to not fall down. Maybe my walls are bent, but they sure don't seem like it. Kind of a giant waste of money in my opinion.
