{"title":"6x8 Modern Vent Covers","description":"\u003cp\u003eA 6x8 vent cover fits an 8\" × 6\" duct opening — the actual hole in your wall, ceiling, or floor, not the size of your old cover's face. \"6x8\" and \"8x6\" describe the same opening; only the order of the numbers differs. Green Vent's 6x8 size is a white aluminum linear slot diffuser with a multi-directional adjustable damper, built for supply air and designed to replace a dated stamped-steel grille without any drywall or duct work. It replaces a dated stamped-steel grille with a modern, low-profile finish that blends into any wall or ceiling.\u003c\/p\u003e\n\u003c!-- Ảnh 1 — Lifestyle install shot.
