One-Touch cleaning system lets you move a single lever to sift ashes into the removable catch pan- no hassle and no mess! In addition the lid and bowl are made of heavy-gauge porcelain-enameled steel and hinged grills are triple nickel-plated. Legs are rust-resistant aluminum as is the high-capacity ash catcher. Handles are made of weather resistant nylon and are glass reinforced. Plus each Weber One Touch Gold grill features crackproof all-weather wheels so you can grill plenty of food in any corner of your yard.
