Wrangler
heres a link heres one kinda like i talked about but its framed where the metal hangs over the side to make it water tight and the smoke pipe comes in the bottom and cover with dirt so the yard rats cant tear it up
on thing its good to put it where you can check the smoke flow from the house and a outdoor thermometer you can see with binos
