ABSTRACT:
The device provides a protective enclosure OR barrier by inserting an internal housing frame into the already existing housing box provided for telephone line access. This frame accommodates a removable coverplate with custom cut holes designed for both lock (cam lock) and plunger switch (i.e. tamper switch). The original exterior cover plate is placed over the front of the inserted invention so as to hold the plunger switch down in position, ready for alarm activation. The installation of the above device prevents or deters a would-be burglar from cutting or damaging telephone lines after removal of the exterior cover plate.
