DryerFlex - New Clothes Dryer Transition Hose from the LintAlert group

Prepare to be impressed!
Until now there did not exist a wire reinforced flex hose that met the code for venting residential dryers and that exhibited 0 Flame Spread and 0 Smoke Development in testing. This flex 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.
Created specifically to accomplish our five objectives: ease of use (very flexible), very efficient (smooth interior walls), fire resistant (meets the very stringent UL2158A Class 0 standard), meets the ICC Residential & Mechanical Codes (M1502, 504), and priced competitively.
Exclusively offered by the people who brought you the LintAlert.
DryerFlex -- Safe, Efficient and Very Flexible Clothes Dryer Transition Hose. The only flexible UL 2158A Class 0 (smoke and flame spread) dryer duct hose that also meets the International Residential & Mechanical Codes (M1502, 504).
