Abstract: An insulator having a torque-resistant or torque-prevailing crimped insulator end fitting; including a method of crimping the insulator end fitting so as to be resistant to torque tending to loosen mounting bolt connections of the insulator. A fiberglass core is located in the insulator and protrudes from the opposite ends of the insulator, and has end fittings seated thereon in close interference engagement, by mounting the insulator through intermediary of the end fittings being attached to power devices by threaded bolts extending from the devices being engaged in the tapped bolt holes. Radially inwardly directed crimping forces are applied to the cylindrical wall structure of the end fittings intermediate the locations of the bosses having the bolts tightened within the threaded bolt holes, and thereby produce a bolt-locking deformation of the bolt holes.

Abstract: An electrical outlet box constituted of a plastic material and having wall structure including a hexagonal recess extending into a portion of the thickness of a wall. A through-hole is drillable within the recess to facilitate passage therethrough of a screw-threaded leading end of a cord grip into the outlet box. As a lock nut is torqued down onto the leading end of the cord grip within the outlet box, a hexagonal flange of the cord grip engages within the hexagonal recess so as to inhibit relative rotation between the cord grip and electrical outlet box to obviate the need for a wrench during the torquing down of the lock nut. This structure avoids the need for a custom designed cord grip and facilitates the use of existing cord grips normally designed for utilization with metallic electrical outlet boxes.

Abstract: A floor box wiring fitting incorporating a novel carpet flange possessing a self-closing flap cover assembly, whereby the fitting is adapted to be cast into a concrete floor of a building for the conductance of electrical power or telecommunication signals between the work spaces of buildings.
