Step 9: Electric Fence Insulator

Picture of Electric Fence Insulator
Cut a small bottle in half. You can use both halves.

Using one half cut a Z groove on the open end. Directly opposite of the bottle, but still on the open end, cut another Z groove, and make sure to make it a mirror image of the first.

Now, on the closed in, make a slit or large hole for your post to run through both sides of the bottle. Near the slit, make two small holes, either side of the post slit. Use this end to wire to the post, and run the electric fence through the Z groove.
what is this i don t understand
it is to keep the electricity in an electric fence from grounding on each of the metal poles it is held up with
