Designed for venting a dryer through the roof, the extra-clearance DryerJack 486 is manufactured with heavy-gauge Galvalume steel like the original model 477, but is taller for use with higher-profile tile or in moderate snowfall zones. The hood’s wide opening, protected from water intrusion by a curved damper, enables efficient airflow, according to the manufacturer. A removable access door facilitates duct cleaning, and a flange with nail holes helps speed installation. DryerJacks are optimally designed for a roof pitch between 3/12 and 12/12, the manufacturer says.
