If you are building a permanent electric fence for cord or wire, these insulators are what you need. The insulators are made of high-quality black plastic with a metal core.
The metal core guarantees a stronger insulator which does not break easily. Insulators without a metal core can break when a lot of force is applied to the insulator. This insulators will keep its shape longer to prevent it from breaking.
