  • Patent number: 4692567
    Abstract: An electric fence holder. Two embodiments can be produced from a common mold cavity. Both embodiments comprise a strap formed of resilient plastic with a wire retaining bracket formed at the center. The first embodiment is longer than the second and has clamps at its ends for engaging the strands of an existing fence. The second embodiment, formed by blocking the outer portions of the mold cavity, has holes in its ends for mounting the strap on a stake that has been driven into the ground. In both embodiments an electrically conductive wire is held by the wire-retaining bracket out of grounding contact with the existing fence or stake. Flexing either strap into a bow for installation locks the conductive wire in place.
