Builder's Best 110696 Saf-T-Duct® Dryer Outlet Box

The Saf-T-Duct Dryer Outlet Box from Builder's Best finishes off dryer vent rough-ins and easily adds or recaptures space in the wall behind your dryer for venting. The unit can be used in-wall (prior to drywall) or on-wall (after drywall is installed). The standard 4 in. round connections allow for the best airflow and connect easier than ovals.
