Today, you can place the dryer flush to the wall without crushing the exhaust hose or restricting airflow. Install the Dryerbox® for safer, roomier and more efficient homes. DB-480 is taller and wider to safely collect transition hose for dryers that sit directly on the floor, as well as those on a pedestal. It can be inverted to vent up or down, but it is installed on the bottom plate for every home.
