An electric fence must be taut to be effective - you need strong posts at the ends and corners, and tough stakes in between. All our electric fencing posts are built for strength, and will last for years even in the toughest conditions.
Use an Anchor post at the start of the fence and for corners. Use a Reel post at the end of the fence. All are available in 2, 3, and 4-line as well as equine variants. You may need several Anchor posts depending on the number of corners but will only need one Reel post.
