While the Metal King Kone is built to last, it might be good to have a couple spare parts laying around--just in case. The King Kone 98/109mm top tray is the supplemental cartridge tray you need to operate the King Kone if you want to have the the option to fill 3/4-gram and full-gram cones, in addition to the half-gram 84mm weight. Just fit the top tray onto the 84mm base tray and you are ready to fill it with cones.
