The New Original PK Grill Aaron Franklin Addition The New Original PK Grill and Smoker, Aaron Franklin Addition is upgraded with retro architecture. The PK300 cook chamber is constructed entirely from Aluminum. Aluminum conducts heat 4x more efficiently than steel, which means heat is dispersed evenly throughout the capsule, eliminating hot spots, giving you the perfect cook every time. The PK300 sets a new standard for the high-end charcoal cooker. It offers unique versatility for low and slow or hot and fast bbq grilling. Built to cook and built to last, the PK3oo is the best and last grill you'll ever own. As always, 100% Original.
