94268 by B&B Molders is a round black Thermovent register designed for heating and cooling air distribution in recreational vehicles. Its adjustable louvers rotate 360 degrees to direct airflow where needed, while the built-in damper allows the air passage to be adjusted or closed. The sleek design conceals mounting screws for a clean ceiling finish. Made for compatible RV ducting, this vent has a nominal 4-inch outside diameter and requires an approximately 4-1/8-inch cutout. An installation kit is included.
