Builder's Best Dryer Outlet Box

The Dryer Outlet Box is used to cleanly finish off dryer vent rough-ins. It solves tight dryer venting by recapturing the space in the wall behind the dryer. Advantages include standard 4″ round airflow connections to allow the best airflow and make connections easier.Update: The Dryer Outlet Box now features six patented Rip Tabs knockouts for easier knockouts. We have also added two Oval knockouts for non-standard connections to existing venting (such as squashed duct) or for using a round to oval adapter. See Spec Sheet for details.
