Build onto the Weber Elevations Tiered Grilling system (sold separately) with the elevations cooking system vegetable basket and frame. Simply fill the basket with your favorite vegetables, season, and place securely into the grill rack. The wire frame attaches to the tiered rack at a raised level off the cooking grate to prevent overcooking. The basket's patented hole pattern prevents warping in the grill. When not working with the elevations system, the vegetable basket can be used directly on the grate.
