Don't damage your vinyl or wood rail fencing just to add an electric fence. ESFencing LLC has an electric fence insulator that removes the need for screws or drills. The Easy Snap Insulator provides a solid and secure platform to run electrical wire and tape. The insulator's locking mechanism can hold almost any gauge electrical wire or width of electrical tape securily in place. The product is made from durable, non-conductive and UV resistant "poly” plastic to withstand weather elements and support challenges of wire and tape fencing. Two models are available, one for large fenced areas, a second for small areas, and available for purchase on the company's Web site. Price: $1.65/ insulator; $5.45/corner connector; discounts available for large quantities. www.esfencing.com.
