Ceiling Support Box for Stove Chimney Pipes

Ceiling support boxes provide a safe passage for the double-wall chimney pipe through the attic, cathedral ceiling, or floor in multi-story homes. They also support the weight of the chimney stack. At ComfortBilt, we make our ceiling support box from galvanized steel and 304 stainless steel to ensure superior corrosion resistance. The Ceiling Support Box can support up to 50 feet of chimney pipe, comes in various dimensions, and includes trim for a finished look inside the room.
