This extra-thick walled Insultube gives better protection for underground wire when using lower power fence chargers. We recommend placing it inside a plastic water pipe and seal all the ends with electrical putty. Some people like to use wraparound insulators without the metal insert or flat side. This can be cut to the length needed for ends and bends. This is also available in 6 inch lengths for use on line and bend posts.
