The Vevor fire pit ring is a heavy-duty carbon steel liner designed for DIY campfire setups above ground or in-ground. Its matte black high-temperature powder-coated finish helps resist rust, corrosion, and wear in outdoor conditions. The 40" outer diameter and 36" inner diameter provide ample room for firewood and airflow. With 8 sectional panels, it assembles quickly using the included hardware. It is ideal for backyards, gardens, patios, camping, bonfires, and holiday gatherings.
