All our snuffer lids are designed for the peace of mind. They will suffocate a fire at the end of the night so you can go to bed without worrying. They can also double as a lid to keep the outside elements out of your pit. They are made using high quality carbon plate steel. They have handles for easy placement on top of your pit as well. Carbon Steel will oxidize and form an outside layer of rust which will help to protect the internal steel and your snuffer will eventually match the same patina as your fire pit.
