The Meat Shelf and Load Panel attach the exact same way to our frame panel. The only difference between the two is that the meat shelf then attaches to the back of the bag vs: the load panel is designed to be used as a stand alone product to haul just about anything you can think of out. They are attached to 1″ webbing loops that are sewn to the frame panel with a quick attach ladder lock buckle. Once we get the buckles in place we almost always leave them in place and just remove the meat shelf or load panel webbing if we want to take them off.
On the pic you can see the two webbing loops that are sewn roughly 8″ up from the bottom of the frame panel. These two loops will connect to the quick attach ladder lock buckles that will be slid onto the webbing ends of either the meat shelf or load panel when you get it.
The following pics detail how to attach the quick attach ladder locks.
