Made from built-to-last cast aluminum these grills are inherently rustproof. The hinges, molded into the grill itself, offer the same long-lasting durability. This near-legendary design is why many 70-year-old PK grills are still used today. The unique patented 4 vent system offers unbeatable temperature and air control while the aluminum gives superior heat retention, saving you money. The unique PK 4-way vent system allows you to grill, smoke, bake, and even have 2 separate cooking zones. Works like a kamado, but it’s lightweight and portable making PK grills perfect for campers, hunters, and tailgaters.
