Besides problems with the type of hose that came with the Bradley, my main problem is I need something more flexible; like plastic, or laminated foil or the flex hose. Mine will have to bend in a lazy "S" shape.
I used the cardboard box for years and still occasionally use it with a 4" laminated foil hose. The Bradley hose is an odd size, it's between 4.75" - 5" in diameter, so you will need a 5" hose if you are replacing the hose on the Bradley Cold Smoke Adapter.
