Duravent 9448D pipe's inner walls are 25% thicker than competitive chimneys for an extra margin of safety. No locking bands or mechanical fasteners required.

DuraTech Duravent's sleek 1 Inch wall design provides for easy installations through 16 Inch on-center framing. For tight installations, a Reduced Clearance Round Ceiling Support Box is available (6 Inch diameter DuraTech only).

Designed for normal, continuous operation at 1000°F flue gas temperatures, DuraTech is subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400°F, plus three ten minute chimney fire tests at 2100°F.
