Whether you're replacing a rusted floor register, adding a return grille with a washable filter, or upgrading a wall or ceiling diffuser, Green Vent builds this size in rust-resistant aluminum and heavy-duty steel. \u003cstrong\u003eMeasure your duct opening — not your old cover's faceplate\u003c\/strong\u003e — before you order, since the visible frame always sits larger than the hole itself.

The Aluminum Floor Return Grille has no damper; it's an open, filtered face built for pulling air back to your HVAC system.\u003c\/p\u003e\n\n\u003ch2\u003eSizing\u003c\/h2\u003e\n\u003cp\u003eDuct openings run from small bedroom sizes like 4x10\" up to larger hallway returns like 12x16\". For a 4x10 (or 10x4 — the same size, listed either direction) floor vent cover, measure the duct opening itself, not your old cover's outer frame — the faceplate is always 1 to 1.5 inches larger per side than the hole underneath it. If your opening runs slightly under 4x10\", such as roughly 3⅞\" x 9⅞\", a 4x10 cover will still fit — the faceplate overlap is built to cover that small a gap.

A duct opening running slightly under 4x10\", such as roughly 3⅞\" x 9⅞\", still fits a standard 4x10 cover.
