Rectorseal RCF24-7 Retrofit Rough-in Flange 24 Inch 7 Inch Opening

Product Description

The RECTORSEAL RCF24-7 is a retrofit rough-in flange engineered to reinforce and properly size diffuser openings in 24-inch suspended ceiling grid systems. The 7-inch central opening provides a stable, accurately dimensioned mount for compatible round neck ceiling diffusers. Constructed from steel, the flange integrates with standard T-bar grid layouts to improve structural integrity and alignment during retrofit installations. Licensed HVAC technicians and sheet metal contractors install this component when replacing or upgrading ceiling diffusers in existing suspended ceiling assemblies where the rough opening requires support or resizing.

This flange is suited for residential and light commercial HVAC applications where 24-inch T-bar suspended ceiling systems are in use. It is particularly useful in retrofit scenarios where an existing ceiling tile opening does not align precisely with the diffuser neck size or lacks adequate framing support. The 7-inch opening accommodates round neck diffusers of the corresponding size, ensuring proper seating and a clean finished appearance at the ceiling plane.

Key Features

• Steel construction provides durable framing support within suspended ceiling grids
• 7-inch central opening sized for compatible round neck ceiling diffusers
• Designed for 24-inch T-bar suspended ceiling module layout
• Improves diffuser alignment and structural integrity during retrofit installations
• Suitable for residential and light commercial HVAC ceiling applications

Compatibility

Designed as an OEM-style retrofit component for use with standard 24-inch T-bar suspended ceiling grid systems accepting round neck diffusers with a 7-inch neck opening.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handling unit and verify airflow has stopped before working at the ceiling diffuser location. The flange seats within the existing T-bar grid opening; ensure the grid is structurally sound before securing the flange. Follow local mechanical codes and manufacturer guidelines for fastener placement and diffuser attachment.
