The Firepit Source has a variety of Lid designs, including Basic and Premium, Round and Square, Stainless Steel and Black. They serve to contain embers and help snuff out the fire when you are ready. They help keep out debris, snow and rain. Keeping the burn area dry also helps when starting your next fire. Limiting the amount of rain going into the firepit also prevents water flowing through the pit onto your patio. You can pick a lid style that looks best for your outdoor living area.
