Abstract
Abstract A filler element or insert for installation in a decorator-type wall plate when the latter are used to cover mounting boxes containing standard electrical controls, the insert being a substantially rectangular element dimensioned to fit within the central opening in the wall plate. The insert in turn includes an aperture usually centrally disposed therein, the latter aperture being shaped and dimensioned to accommodate the extending or projecting portion of a desired electrical control. The insert also includes means disposed on its edge portion for providing a luminance mask or visual discontinuity between the front surface of the decorator plate and the front surface of the insert. Means are provided for securing the insert in the aperture in the wall plate.
