Abstract

An electrical wiring box arrangement comprises a non-metallic wiring box having a channel running a portion of the length of each end wall for slideably receiving a gripping member. The gripping member has two opposed body members each having a sloping face for interacting with sloping wall portions of the box wall channel, each body member further having a curved face for engaging the mounting screw of a wiring device. The mounting screw of a wiring device passes into the box wall channel and is engaged between the body portions of the gripping member. As the mounting screw is turned, the gripping member is drawn up into the box wall channel, the sloping walls of which urge the two halves of the gripping member toward one another, increasingly binding the body members down on the mounting screw.
