DryerFlex combines the ease of use and flexibility of the wire-bound
foil flex with the fire resistance and airflow efficiency of semi-rigid
aluminum flex. 48 inches of the safest, most efficient and easiest to
work with clothes dryer transition duct on the market. This transition
duct meets the very stringent Underwriters Laboratories UL2158A standard that the ICC Residential & Mechanical Codes require.
Not your typical wire-bound foil flex
Accommodates all 7 DryerBox models
Impressive stretch to compressed ratio
Maintains the full 4" inside dimension
line, this flex combines all the positive aspects of semi-rigid and
foil flex and eradicates the unpopular aspects of semi-rigid and foil
flex like air flow efficiency, fire containment, recoil ratio and bend
radius. Prepare to be impressed with this hybrid flex product.
Popular with OEM installation contractors, dryer vent cleaners, and appliance repair crews, DryerFlex is now the preferred transition duct for contractors nationwide. For them, it minimizes callbacks and makes
installation a breeze.
The DryerFlex Advantage
with all aluminum ribbon, DryerFlex fire-rated duct is as flexible as
"slinky" foil flex yet stronger than semi-rigid aluminum, making
installation easier and every laundry room safer. Quite simply,
DryerFlex provides the best functionality of the old transition ducts
without any of the defects. DryerFlex always maintains its four-inch
diameter whether fully extended or compressed. This smooth interior
allows the dryer to perform at peak efficiency. It's strong aluminum
ribbon protects against crushing and flame-spread. Choose DryerFlex for
exhaust duct that's safe, efficient and easy to install.
Choose the Highest UL Fire Resistance Class For
safety reasons and added peace of mind, only UL2158A listed ducting,
like DryerFlex, should be used to connect the dryer's exhaust system
(non-listed hose commonly used to vent bathroom fans should never be
used). While building code and dryer manufacturers all require a UL
2158A listed transition duct, there are differences upon further
testing. It is very common to find listed material that is fairly safe
but does develop smoke and flame spread at lower temperatures. DryerFlex’s UL Listing is further substantiated by its ability to minimize smoke and flame emission as this material withstands fire exposure up to 482° in a testing atmosphere.
