Rectorseal A301HM12X4 Sidewall Register 12x4 White Aluminum

Product Description

The RECTORSEAL A301HM12X4 is a white aluminum sidewall supply register with adjustable curved blades, designed for rectangular duct openings in residential and light commercial HVAC systems. Built from corrosion-resistant aluminum, it offers a lightweight and durable alternative to steel registers in supply air applications. The 12-inch by 4-inch face dimension fits standard duct rough openings of the same size. Adjustable curved blades let technicians set the airflow direction horizontally or at an angle to suit the room layout and improve air dispersion into the occupied space. Licensed HVAC technicians and mechanical contractors are the typical installers.

This register is suited for rectangular sidewall supply applications in forced-air systems. It works in residential ducted split systems, fan coil units, and air handler installations where a clean, paintable white finish is required. The curved blade design promotes even air distribution across the room rather than directing a concentrated jet stream. It is appropriate for new construction, renovation, and replacement of existing sidewall grilles and registers where a standard 12-inch by 4-inch duct collar is present.

Key Features

• Adjustable curved blades allow field-set airflow direction for optimized room air distribution
• Corrosion-resistant aluminum construction keeps weight low and extends service life
• 12-inch by 4-inch face dimension fits standard rectangular duct openings
• White finish integrates cleanly with painted walls and standard interior finishes
• Sidewall supply configuration compatible with horizontal discharge HVAC applications

Compatibility

Designed as an OEM-style replacement or new-installation sidewall supply register for residential and light commercial forced-air HVAC systems using standard 12-inch by 4-inch rectangular duct openings.

Installation Notes

Installation is performed by licensed HVAC technicians or mechanical contractors. Power down the air handler or furnace at the disconnect before removing an existing register or accessing the duct collar. Secure the register to the wall or duct flange using the manufacturer-provided hardware and verify the blade adjustment holds position before restoring airflow. Follow local mechanical codes and ACCA installation guidelines for supply air register placement and throw distance.
