Grote’s Snap-In Cover Plates are designed for retrofits and lighting upgrades. The plates are engineered for fast, easy installation with snap tabs that accommodate plate thicknesses from .125 to .250 of an inch. They are available in two standard sizes (4-inch round, 6-inch oval) and colors (gray, black) and come in sets of two. Each set includes a foam gasket to help minimize moisture intrusion and a flange mounting hole pattern for screw mounting and added security.
