Abstract: A tile wall cover for electrical outlet boxes includes a ringlike flat plate having a large central opening therethrough. A ringlike extension is secured to the plate around the opening. The extension is formed from a pair of substantially identical generally U-shaped members each having a base and opposite first and second legs. The first leg on each member has an offset terminal end portion which is offset toward the second leg a distance generally equal to the thickness of the material from which the member is made to form a rabbet on the outer surface of the first leg. The pair of members are reversely positioned with the rabbet on the first leg of each member receiving the terminal end portion of the second leg on the other member.
