RB-WB

American Aldes RB-WB Register Boxes are designed to accommodate an automatic, self-regulating Constant Airflow Regulator (CAR-II), which is sold separately. A CAR-II automatically regulates airflows in duct systems to constant levels because it responds to duct pressure. The CAR-II requires no electric or pneumatic sensors or controls. To order register boxes with CAR-IIs, specify CERB-WB-II for exhaust or return air, or CSRB-WB-II for supply air.

The RB-WB is constructed of heavy-gauge galvanized steel with an extended duct collar that allows attachment of flexible or rigid duct. Optional flush-mount exhaust grilles and supply grilles are sold separately.
