This is the gateway from the Jet Boil PCS to the rest of the world. You simply fold out the pot support and it's tabs center the pot support on the wind screen. The stabilizer snaps onto two different sizes of fuel can and makes the stove harder to tip. With this you can use almost any pot you want as long as it isn't too heavy. If you pack it up like you are supposed to, the parts fit inside the PCS and are protected so they will not break. The way the pot support fits over the fuel can when folded up, keeps it from being bent. As for the stabilizer, it's hard to break as it is.
