Use of Hotwire and attachments
These plastic pieces on the top of the fences? Those are for the hotwire. A lot of people do put the hotwire along the top to keep the horses from playing with each other too much. Some people put hotwire here [midway down the fence] if you want to keep your horses off your fences or if they're playing too hard.
