The RECTORSEAL 103O08X04 is a 3-way stamped steel ceiling and sidewall register designed for residential and light commercial HVAC air distribution applications. Built with 1/2-inch stamped louvers set at a 40-degree blade pitch, this register delivers directional airflow control in three directions from a single outlet. An aluminum opposed blade damper allows airflow volume adjustment directly through the face of the register using a standard tool, without removing the grille. The white finish integrates cleanly into standard ceiling and sidewall installations. Licensed HVAC technicians and HVAC installers are the primary trades specifying and installing this register.
This register suits forced-air residential systems and light commercial HVAC applications where ceiling or sidewall supply outlets are required. The 8-inch by 4-inch face fits standard duct openings of that nominal size. The 3-way louver pattern makes it suitable for corner or mid-room placements where airflow needs to be directed across multiple axes from a single supply point. The tool-operated damper allows volume balancing after installation without additional hardware.
Designed as an OEM-style replacement or new-installation register for standard 8-inch by 4-inch supply duct openings in residential and light commercial forced-air HVAC systems.
Installation is typically performed by a licensed HVAC technician or qualified installer. Shut down the air handler or furnace and confirm the system is de-energized before beginning duct or register work. Verify the rough duct opening matches the nominal 8-inch by 4-inch register size before mounting. Secure the register according to local mechanical code requirements and confirm damper blade operation before returning the system to service.
