With a thoughtful four-level adjustable cooking grate, these grills will accommodate the heat needs of anyone! The 620 Rotating Pedestal Grill by Ultra Site offers a cooking area of 280 square inches while the 630 bumps that total space up just a bit to 300 square inches. Cool-coil handles have been added to the grate as well so it is easy and safe to adjust as needed. The high-temp black powder-coated firebox has been made from steel and MIG welded. To ensure safety of users and the environment, an in-ground mount is required for both models. A hot-dipped galvanized firebox is optional.
