Panduit RFG3DY Raised Floor Air Sealing Grommet

Product Description

The PANDUIT RFG3DY is a raised floor air sealing grommet designed to close cable pass-through openings in raised access floor tiles. By sealing around cables and conduit bundles at floor cutouts, the grommet blocks uncontrolled airflow between the plenum and the equipment room above. This reduces bypass air loss, supports hot-aisle and cold-aisle containment strategies, and helps data center and server room operators maintain consistent cooling efficiency. The RFG3DY is sold as a single unit and is installed by data center technicians, facilities engineers, and structured cabling professionals working on airflow management projects.

This grommet is used in raised access floor environments, primarily in data centers, network operations centers, and enterprise server rooms. It is installed at floor tile cutouts where power, network, or fiber cables pass through, sealing the gap between cables and the tile opening. Proper use at each cable entry point prevents conditioned air from bypassing IT equipment and helps maintain the pressure differential needed for effective under-floor cooling distribution.

Key Features

• Seals cable pass-through openings in raised access floor tiles to control bypass airflow
• Supports hot-aisle and cold-aisle containment by reducing unmanaged air leakage at floor penetrations
• Accommodates cables and conduit bundles passing through floor cutouts
• Single-unit packaging allows targeted deployment at individual floor tile openings
• Designed for professional installation in data center and network facility environments

Compatibility

Designed as an OEM-style replacement and standard fitment for raised access floor tile cable pass-through openings in data center and network facility airflow management applications.

Installation Notes

Installation is typically performed by data center technicians or structured cabling professionals. Before installing or repositioning floor tiles, power down any equipment that could be disrupted by accidental cable disturbance and coordinate with facilities staff regarding active under-floor air systems. The grommet should be fitted around existing cable bundles at the tile cutout and seated flush with the tile surface to maintain an effective air seal. Follow applicable data center infrastructure and airflow management guidelines for your facility.
