Product Details:
The DuraTech Class A Square Cathedral Ceiling Support Box is used to support the DuraTech Class A Chimney Pipe when passing through a cathedral ceiling. The DuraTech Chimney Pipe twist-locks into the interior of the support box providing a positive connection to the chimney pipe.

The 11" box can accommodate a flat ceiling thru a 4/12 pitch, the 24" box can accommodate a 7/12 thru 13/12 roof pitch and the 36" support box can accommodate a 14/12 thru 20/12 ceiling pitch. An adjustable 2" wide ceiling trim collar is included with each box to provide a finished look in the living space.
