Abstract
A protective ring apparatus includes a back plate and a riser wall which projects outward from the back plate. The riser wall is located peripheral to a back plate central access channel. A front frame is connected to a top portion of the riser wall, and the front frame defines a front frame access channel which is in registration with the back plate central access channel. A pair of twist links, located along a common link axis, are connected to opposite sides of the front frame. A removable protector plate is connected to the pair of twist links and, prior to its removal, covers and prevents wires in an open electrical box from being cut by a cutting tool used to cut a window in a sheet of drywall to be installed around an electrical box framed by the plaster ring apparatus.
