The watertight collar (silicone sealed) extends above the nailing flange.
Combined with the hood shape, damper design and built-in gutter system,
DryerJacks provide added protection against water intrusion.
Shorter duct runs, created by venting the dryer straight through the roof, can improve drying efficiency and lessen lint buildup. Until now, however, there were no roof terminations that met all of the stringent dryer venting requirements. The new DryerJacks are engineered specifically for dryers. They meet or exceed all code requirements and deliver superior airflow efficiency.
