The Lutron screwless wall plate mounts flush against the wall and provides a clean, streamlined appearance. Unlike conventional wall plates with visible screws, the Lutron Claro 1-gang wall plate features a two-part configuration - a backing plate that attaches to the wall and vanity plate that easily snaps to the backing plate, covering the screws. The oversized wall plate hides gaps around wallboxes and works with most large toggle light switches and dimmers.
