ABSTRACT:
A number of conveniently manufactured and easily installed fastening devices are disclosed for use with conventional cabinets and enclosures. Each of these devices inherently utilizes the physical fact that a child's hand span is smaller than that of an adult. The devices make it impossible to open an enclosure by individuals having a hand span less than a predetermined length. Each fastening device, or pair of devices, includes a spring-biased latching means that engages a fixed strike plate internal to the enclosure being protected. Latch release means are provided on the outside of the enclosure and these latch means are operable in conjunction with a further release means, both combining to successfully open the enclosure.
