Constructed from sheet metal with a brown powder-coated finish, it fits into standard floor openings to provide a return-air intake point while accepting a filter insert. The grille measures 24 inches in length by 4 inches in width, making it a fit for narrow floor register openings. Edges are finished without sharp surfaces, reducing the risk of cuts during handling and installation. Each unit is hand inspected before packaging.\u003c\/p\u003e\n\u003cp\u003eThis grille is suited for forced-air HVAC systems where the return-air or supply register is located in the floor.
