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 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 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 can often eliminate the need for a hard 90 degree elbow making your overall duct run shorter and more efficient.
