The ProSelect PS3WW12P is an 12 in. x 4 in. residential supply register engineered to facilitate three-sided airflow distribution in central heating and cooling applications. By breaking the supply air stream into a 3-way pattern, this register maximizes room circulation and prevents uncomfortable direct drafts from blowing onto occupants. This multi-directional delivery is ideal for small to mid-sized rooms where thorough environmental air mixing is required.
Manufactured from stamped steel, this ceiling and sidewall register offers reliable structural performance and resistance to the typical physical wear encountered during household use. The durable white finish delivers a clean appearance that fits cleanly into modern painted drywall ceilings or standard room wall surfaces. The integrated louver system is structured to sustain steady throw velocities while helping to keep system static pressure within nominal bounds.
This 12 in. x 4 in. component is suitable for both ceiling and sidewall placement, providing versatility for diverse residential duct layouts and framing designs. HVAC contractors specify this model during new branch additions or routine trim upgrades to improve regional air blending. Verify that the inner throat measurement matches the 12 in. x 4 in. specification prior to ordering to guarantee a secure drop-in fit.
