One of the biggest contributors to dryer lint fires is vent restriction. Because code forbids the use of screens and requires a damper for dryer exhaust, installers previously had to alter the vent and / or settle for bad performance.
Today, you have a code compliant option right out of the box.
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 DryerJack® is engineered specifically for dryers. They meet or exceed all code requirements and deliver superior airflow efficiency.
Built to the same quality standards as the Dryerbox®, DryerJack performance stands the test of time.
