DryerFlex by GREENCO2
With common transition ducts having some pros and cons, it was time to create a product that featured the best of both worlds. Today, DryerFlex by GREENCO2 is the only UL-2158A transition duct available that's as flexible as foil yet features the same airflow efficiency and fire safety as semi-rigid aluminum.
DryerFlex by GREENCO2 retains a full 4" opening whether compressed or stretched which helps ensure continuous airflow without creating lint catching points. Because of its tight turns, using DryerFlex by GREENCO2 can often eliminate the need for a hard 90 degree elbow making your overall duct run shorter and more efficient.
