Notched Bar Cow Trainer is made entirely of stainless steel for long life and durability. May be used with standard number 12 or number 14 electric fence wire. Can be used with the 514-1700 Controller.To install, string electric wire 18" to 22" from back of stanchion line.

These trainers are available with 2 types of hanger clips that attach to the wire:
Standard clips - these clips are an older design and use a staple to secure the clip to the wire (a little clumsy and not as simple as the Ludwig clip.
Ludwig clips - these are much simpler clips that just snap on and stay in place.

Clips are interchangeable so if you have older trainers that use the standard clip you can just order the Ludwig clip.
