I have a 36” aluminized steel ring and it takes about 28 of my concrete blocks to surround it. There are more blocks available if you’d like to add another coarse. The steel ring is $100 and the blocks I usually sell for $2/block. I’ll give you a little discount and sell the ring and blocks needed for 2 rows for $150. I don’t expect this to last long. This fire pit will definitely look good in your yard or at your cabin up north. If this ad is still up, they are available.
