Semi-rigid aluminum duct is ideal when all aluminum duct is required by code in some gas and electric dryer applications. Totally noncombustible with a maximum operation temperature of 435 degree F.

Flexible aluminum ducting This Class 0, non-combustible duct is constructed of a special aluminum alloy that prevents corrosion and metal fatigue The machine fabrication produces a continuous lock seam that permits the duct to be pulled open, compressed, bent, and re-bent without developing leakage 7" diameter for HVAC and kitchen-range hood venting Semi rigid but flexible for easy installation Fire resistant material Holds it shape for improved air flow
