  • Publication number: 20030145799
    Abstract: An animal enclosure system is disclosed utilizing a coated metal wire grid mounted within a frame formed of horizontal and vertical support members. The end of each wire on the wire grid has a captive termination that allows the wire grid to be installed into an opening, hole, or channel of the support members. The wire grid may also incorporate a hinge area formed by dividing the horizontal wires into two portions and wrapping the inner terminating points around a particular perpendicular vertical wire near the mid-point of the body of the wire grid. The hinge allows the wire grid to be folded, facilitating easier handling, storage and transport of the enclosure in its disassembled state. When the wire grid is assembled with the support members, along with corner pieces, it forms a single panel of the animal enclosure.
