ABSTRACT:
A protective insert for protecting wires and other contents of a utility box such as an electrical or communication wiring box, from damage during construction, particularly when cutting openings for such boxes in wallboard that has been placed onto studs. The insert is made to utilize the only standard dimensions in utility boxes, namely, the distance between the threaded bores used for fastening switches, receptacles or other fixtures. The protective insert is easily placed into utility boxes using two ribbed posts or shanks that fit into the openings of the box with a fit that retains the insert in place. The insert is easily removed, and it also protects the threaded bores in the box that are used for supporting switches, receptacles, light fixtures, or the like.
