  • Electric fence insulator
    Patent number: 6380490
    Abstract: An insulator for mounting an electric wire to a round vertical post. The insulator main body includes an outwardly opening slot through which the round post may be moved as the insulator is removed from the post. A nut is threadedly mounted at the slotted end of the main body limiting movement of the round post within the slot. A spacer within the slot limits inward movement of the slot walls. Various embodiments of the spacer are disclosed.
