Abstract
Electrical wiring box arrangments comprise a wiring box with a wall structure having a channel for slideably receiving a gripping member for engaging the mounting screw of a wiring device mounted in the box. The gripping member comprises a body having two opposed elements which engage and grip the threads of the mounting screw. Inwardly tapering wall portions of the box wall channel urge the two gripping member elements toward one another as the mounting screw is tightened, insuring a firm grip between the mounting screw and the gripping member.
