- Designed for condos, apartments, or anywhere space is at a premium. The American Outdoor Grill In- Ground and Patio Post Mount units pack a lot of grilling enjoyment into smaller spaces (432 square inches). The In-Ground Grill models must be cemented into the ground. Pedestal models may be bolted to a deck or concrete slab. Both feature a backburner, warming rack and dual side shelves (standard). The optional stainless steel tank shield is designed to conceal the unsightly propane tank while a safety chain keeps the tank securely in place.
