Description Give yourself some space. The P.A.L. Pop-And-Lock Folding Front Shelf XL attaches to your P.A.L. rail to offer up extra room for prepping, plating, resting meat, and more. And when itâs not needed you can fold it down to keep it out of the way, yet still accessible at a momentâs notice. This XL shelf size is ideal for larger grills and big feasts. *This shelf is not compatible with the Silverton XL grill.
