Step-by-Step Installation
-
Measure the opening : Measure the duct opening carefully at the baseboard level. Measure the width first, then the height. Always measure the wall or baseboard opening, not the old vent cover.
-
Remove the old register : Unscrew and remove the existing register or grille. Clean the duct opening and the surrounding baseboard area to remove dust, debris, or loose material.
-
Position the 1BB register : Place the 1BB corner baseboard register over the opening. Make sure it sits evenly against the baseboard and that the adjustable airflow lever is easily accessible.
-
Secure the register : Use the included screws through the pre-drilled holes to secure the register in place. Do not overtighten the screws. A snug fit is enough to hold the register securely without damaging the frame.
-
Adjust the airflow : Use the adjustable lever to control the airflow volume. Test the airflow and adjust as needed for your room.
- Check operation : Confirm that the register is firmly installed and that the airflow lever moves smoothly.
Easy Maintenance
The removable faceplate allows quick access for routine cleaning and maintenance, helping keep your HVAC system operating efficiently. The integrated adjustable damper lever lets you regulate airflow easily, providing greater comfort while maintaining consistent ventilation throughout the space.

What is the difference between the 1BB and BRA baseboard models?
The 1BB is a supply diffuser register with an adjustable damper and 3-way airflow, designed for delivering conditioned air. The BRA is a return grille without a damper, designed to extract air back into the system. Choose 1BB for supply applications and BRA for return applications.
Does the 1BB register include a damper?
How does the 180-degree round design help airflow?
The curved blade pattern distributes air more evenly across the room, improving circulation.
Can I install the 1BB on a regular wall without a baseboard?
While designed for baseboard installation, the 1BB can be installed on any sidewall if the duct size matches. The low-profile design works well in any floor-level application.
Is the 1BB suitable for commercial use?
Yes, the heavy-duty steel construction, integrated damper, and durable powder-coated finish make the 1BB series suitable for both residential homes and commercial buildings that require continuous operation.
