Thanks to these reusable aluminum drip trays from NAPOLEON, your Rogue 425 grill will stay clean longer and maintenance will be easier. These aluminum drip trays are easily placed in the grease drip tray of your Rogue grill to catch the grease and residue that is not burned off during grilling. The tray should be checked and replaced every 4 to 6 grilling sessions, depending on how much grilling you do. This will ensure optimal grill care.
