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 support boxes are available in 11″, 24″ and 36″ lengths to accommodate an array of ceiling pitches. 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.
Use the DuraTech Single Wall Snap Lock Adapter with Trim to connect the ceiling support box to a single wall stove pipe. All sizes of the support boxes will fit between standard 16″ on center ceiling joists.
