I am running stove pipe through a drop ceiling. I have a Franklin stove with 8" pipe off it. drop ceiling has tile and 4" of insulation and about 3 ft to metal roof. I live in country I have converted a metal building into a house. The area above the drop ceiling is wide open until you get to metal roof. I need a ceiling support box that I can attached to framing of drop ceiling and extends up above insulation I would like the support box to also work as an attic shield above the insulation and drop ceiling.

I have 2, 8" pipes that I need to put through a roof of a garage ceiling. I am looking for 2 square ceiling support boxes. Do you have something that would suit my needs here? If so, how much would that run me?
I will also need the outside triple wall pipe and I wondered if you also have that. I believe I need a 3 foot piece of that.

Answer:The part you mention, CPF-69880, is generally the Cathedral Ceiling Support Box that we recommend to customers that need to support triple wall pipe as it passes through their ceiling. We also have several different brands of triple wall pipe available. The catch with the pipe and support boxes that we carry is that they are only recommended to be used with like components. It is not recommended to mix and match brands of piping components.

I am looking for a ceiling support box for my mobile home. The ceiling joists are 13 1/2" apart and the ceiling depth is 20". Do you have a box that will work for this?

Answer:Unfortunately, the 8-inch ceiling support boxes we carry will all be too large to fit into a 13 1/2 inch wide span. It will be necessary to either notch the joists to allow the box to fit or to cut the joists and box them to adjacent ceiling joists to maintain structural integrity. This is a fairly common practice and often must be done for larger air cooled chimneys.

Will this work on a flat ceiling?
By Collin C. - NFI Master Hearth Professional on September 4, 2012
While it is usually recommended to use a round ceiling support for a flat ceiling, there is no reason that a ceiling support box cannot be used. The box can even be trimmed on the top side, so that you may recess it further into the ceiling.
The Duraplus Round Ceiling Support
is another option that is commonly used on flat ceilings. Either item will offer sufficient clearances to combustible materials.

How does 8" black stove pipe finish at the ceiling support box? Do I need special pipe or adapter?
