Rectorseal A5405SDRD12 Directional Diffuser 24x24 2-way

Product Description

The RECTORSEAL A5405SDRD12 is a 2-way corner directional ceiling diffuser designed for use in commercial and residential HVAC air distribution systems. Built with an aluminum panel face measuring 24 inches x 24 inches, it features a 12-inch diameter round neck and integrates a steel square-to-round transition, making it a complete ceiling module assembly. The white finish blends cleanly into standard ceiling grids. HVAC installers and sheet metal contractors typically specify this diffuser for corner-mounted supply air applications where directional airflow control is required in a finished ceiling environment.

This diffuser is suited for ceiling module (CM) installations where a 24 x 24 inch ceiling tile footprint is standard. The 2-way directional configuration makes it appropriate for corner zones in open-plan offices, retail spaces, hotel rooms, and similar commercial interiors. The 12-inch face opening paired with a 12-inch diameter round neck allows connection to round ductwork or flex duct serving supply air registers in light commercial or residential forced-air systems.

Key Features

• 2-way directional airflow pattern engineered for corner ceiling placement
• Aluminum panel construction with a clean white finish for standard ceiling grid compatibility
• 24 x 24 inch ceiling module size fits standard commercial ceiling grid openings
• 12-inch diameter round neck for direct connection to round or flexible ductwork
• Integrated steel square-to-round transition included as part of the assembly
• 12 x 12 inch face opening for focused directional supply air delivery

Compatibility

Designed as an OEM-style replacement or new-installation diffuser for standard 24 x 24 inch commercial ceiling grid systems utilizing 12-inch round duct connections in corner supply air applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor familiar with commercial air distribution systems. Shut off the air handling unit and secure the duct system before connecting or repositioning the diffuser assembly. The round neck connects to supply ductwork using standard drive cleats, sheet metal screws, or duct tape rated for HVAC use per local mechanical codes. Ensure the ceiling grid supports the combined weight of the diffuser and duct connection before final seating.
