Rectorseal 403M12X04 Supply Register 12 X 4 Inches White

Product Description

The RECTORSEAL 403M12X04 is a 3-way supply register built for rectangular duct openings that require controlled, multi-directional airflow distribution. Constructed from stamped steel with a white powder-coated finish, it measures 12 inches by 4 inches at the face and fits standard sidewall or ceiling installations. The S-curved blade configuration promotes improved air mixing and directional spread across the conditioned space. An integrated multi-shutter damper allows airflow balancing directly at the register without additional hardware. Licensed HVAC technicians and mechanical contractors install this register as part of residential and light commercial supply air systems.

This register is suited for sidewall or ceiling supply openings in residential and light commercial HVAC applications where adjustable, three-direction airflow is required. The 12-inch by 4-inch face size accommodates standard rectangular duct terminations. The multi-shutter damper makes it practical for zones where supply airflow needs to be trimmed without returning to the air handler or damper box. The white powder-coated finish resists corrosion and blends with standard interior trim in residential settings.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified mechanical contractors. Shut down the air handling unit and close the supply damper serving the branch before removing or installing the register. Secure the register to the wall or ceiling surface per local mechanical codes, ensuring the face plate seats flush against the finished surface to prevent air bypass. Adjust the multi-shutter damper blades only after the system is restored to operation and airflow is confirmed through the duct branch.
