    Sorry guys I should have been a little more clear.I am building my first rf smoker.I am using a 80 tank and the calculator calls for 15 inches if  I want to use a 5 inch pipe.We use alot at work and so 5 inch is free.my question was about a chimney cap of sorts to keep rain out and critters.I can get 4 inch pipe but I would have to step the length up.or maybe run  2  4 inch pipes?[​IMG]

    Now you want like a rain guard for the top of your smoke stack. Right. Why can't you just get somew threaded rod and a piece of plate and bend it in maybe a 1/8th round and then weld the rods to the stacks (and you can use 5" pipe) and then to the plate. I have seen them on smokers all over the place.

    yes it doesnt have to be air tight, would be easy to make something up.

    ya might want to try this....

    all ya need to do is weld a threaded stud inside of the pipe and with a piece of 1/8" steel plate with a hole in it to go on the stud....then use a nut with an acorn style top to it from an auto parts store, chrome even....

    then you just need to open and close it how ever much you need it to be [​IMG]  ...........bob

    You could use one like this with a small amount of small gauge mesh on the inside to keep the critters and large bugs out. And should keep all the rain out unless you are in a monsoon.
