I would love to hear your thoughts on a new insulator that is available for equine and livestock owner with vinyl or wood rail fencing. It's a patented product that snaps easily over the rails of the vinyl or 2x6 wood rail fencing. No drilling holes or screws in our beautiful white vinyl fencing. The website gives a complete video of how it works and more specific information on it. Go to www.esfencing.com. Here is an image of it.
