Copper Wire Theft Protection Method And Apparatus For Wall-Mounted Pull Boxes

摘要

A kit and method for preventing theft or wires interconnected within a pull box of the type which is mounted in a concrete wall or other such concrete body includes a steel cover plate having a downwardly protruding pair of locking tubes that receive the upstanding shanks of a pair of studs anchored in the concrete body. Each locking tube includes a spring which urges locking pins extending upwards from a floating locking plate through perforations through a fixed locking plate into bores in the lower face of a novel locking collar-nut threaded onto a stud to fasten it to the lid, thus locking the nut from being unthreaded from the stud.

1. A method for thwarting access to electrical wires interconnected within a pull box-type electrical junction box enclosure of the type which is mounted in a recess in a wall or other concrete body to thereby protect against theft of wire from the enclosure, said method comprising the steps of:
a. aligning at least a first clearance hole in a bottom wall panel of a junction box shell with a first anchor bore in said concrete body below said bottom wall panel, b. inserting a first elongated threaded stud into said first anchor bore through said first clearance hole in said bottom wall panel of said junction box shell, c. fixedly attaching said first stud to said concrete body, d. positioning a first downwardly depending tubular locking tube of a transversely disposed security lid coaxially over said first stud, e. lowering said lid to receive an upper end of said shank of said first stud in a bore through said first locking tube sufficiently far for a lower transverse end wall of said locking tube to seat on a stop member located a pre-determined distance below the upper end of said stud, and f. fastening said first locking tube to said first stud.
