Dual-wall design uses a layer of air to insulate the cooler outer wall from the high temperature inner wall, improving draft and eliminating hot spots.
Corrosion Resistant
Galvanized steel outer wall resists atmospheric corrosion while the self-oxidizing aluminum inner liner resists condensation and heat.
Lightweight Design
Lightweight design (one foot weighs only about 4.2 pounds) features patented "Snap-Lock" connection system and rolled male ends for easy handling and installation and a tighter, strong fit.
Other Features
Engineered to prevent condensation within the vent or at any appliance draft hood. Safety-tested to Underwriters Laboratories UL-441 to 470°F maximum temperature. Optional stainless steel liner is also available.
