Metal-fab mffg820 Floor Filter Grille 8x20 in Brown

Product Description

The METAL-FAB mffg820 is a sheet metal floor filter grille designed for residential and light commercial forced-air ventilation systems. It mounts flush in floor openings to direct conditioned air into the living space while accepting a standard filter insert. The grille is finished in a powder-coated brown to blend with common flooring surfaces. Sheet metal construction keeps the unit rigid under foot traffic, and all edges are finished to eliminate sharp surfaces. Licensed HVAC technicians and general contractors install this grille as part of new construction or as a direct replacement in existing duct systems.

This grille is suited for floor-mounted supply or return applications in residential homes and light commercial spaces. The 8 x 20 inch opening size fits standard framed floor register cutouts of the same nominal dimension. The brown powder-coat finish coordinates with hardwood, laminate, and tile flooring. Each unit is hand inspected before packaging to verify finish quality and smooth louver operation.

Key Features

• Sheet metal construction provides rigidity and durability under normal foot traffic

Compatibility

Designed as an OEM-style replacement or new-construction floor filter grille for standard 8 x 20 inch floor register openings in residential and light commercial forced-air duct systems.

Installation Notes

Installation is typically performed by an HVAC technician or general contractor. Shut down the air handler or furnace before removing an existing grille to prevent debris from entering the duct. Secure the grille to the floor framing per local mechanical code requirements. Verify that the filter insert, if used, seats fully before restoring airflow.
