Four steel panels bolt together to form a round fire pit ring insert that gives DIY users a defined fire area for in-ground or above-ground setups. The 10-in high wall helps contain burning carbon or firewood while allowing air to circulate for steady combustion. With a 36-in outside diameter and 30-in inside diameter, it offers ample room for a backyard fire. The 2 mm thick steel with a powder-coat surface stands up to frequent outdoor use and high temperatures.
