  • Patent number: 6131885
    Abstract: A plastic fence post for use in electric fences, which can be quickly and easily adjusted in height to permit changes in the height of the fence, and which can be used with different types of fence strands. The fence post includes an elongated, T-shaped plastic lower post member having one end adapted for insertion into the ground and an opposite end having a T-shaped slot formed therein. A plastic upper member, which can either be an upper fence post or a post cap, includes a T-shaped tongue extending therefrom that is secured within the T-shaped slot so as to secure the upper member to the lower post member. A pin extends through aligned holes in the end of the lower post member and the T-shaped tongue in order to fasten the upper and lower members together. The height of the fence can be increased by disposing the tongue of the upper fence post within the T-shaped slot, and using the pin to secure the posts together.

  • Patent number: 5959255
    Abstract: An insulator for attachment to a chain link fence and that is configured so as to support fence strand members generally parallel to the ground. The insulator includes an elongate body portion having first and second ends, with a mounting structure, preferably a clip structure, at the first end of the body portion for attaching the insulator to the chain link fence. A fence strand retainer is disposed at the second end of the body portion for retaining the electric fence strand member. The fence strand retainer is oriented at an acute angle relative to the mounting structure, with the acute angle preferably being about 45 degrees due to the pattern of the mesh forming the chain link fence, such that when the insulator is mounted on the chain link fence and the electric fence strand member is held by the fence strand retainer, the fence strand member will be oriented substantially parallel to the ground.
