8.5 x 10-1/16 Wide Flange Modern Wall Vent Cover | Flush Mount Steel Grille

Our Wide Flange Modern Wall Vent in Powder-Coated Matt White is built for older homes where the wall around the duct opening is damaged, uneven, or larger than a standard grille can cover. The body fits an 8 1/2 x 10 1/16 inch wall opening, and the extra wide flange gives a finished cover of 12 1/2 x 13 1/16 inches. Specifications: Wall opening (body size): 8 1/2 x 10 1/16 in Finished cover size: 12 1/2 x 13 1/16 in Flange: 2 in on each side of the 8 1/2 in dimension and 1 1/2 in on each side of the 10 1/16 in dimension (standard vents have a 0.55 in lip) Material: 1.2mm (18 ga) Cold Rolled Steel, powder coated matt white Use: return air or supply air Key Features: Covers old openings: The wide flange hides rough edges, old grille outlines and patched drywall around the opening.

Certified ratings tested to ASHRAE 70-2006 and ADC 1062 will supersede this data once testing is complete. Airflow (CFM) is derived by continuity from the rated net free area at standard air density of 0.075 lb per cubic foot under isothermal conditions. The net free area shown is the conservative perimeter opening of the smaller 8 x 10 body. This body is larger, so delivered airflow meets or exceeds the listed values. Static pressure is a conservative calculated estimate referenced to the free-area velocity and carries an added margin. Tested values are expected to be lower. Throw values are estimates scaled to this product and are pending TRM ASHRAE 70 certification. Sound rating data is pending laboratory test. Dimensions are nominal and subject to manufacturing tolerance. Consult TRM Metal Products for applications beyond the conditions shown.

Selection of the product and verification of its suitability for a given application are the responsibility of the system designer and purchaser.
