The multilevel lift has a number of functions in your BBQ. The standard stainless steel grill grate fits both the bottom ring and the top holder, so you can place your grill higher in the Yakiniku.
In combination with the half heat delfector and the half stainless steel grids, you can use the lift to fear multiple settings at the same time in the Yakiniku. this way you can grill indirectly at the same time. For this you need the half grill and half deflector.
The lift can also be used in combination with the basic grill grille and the half deflectors.
