Here at the Rawles Ranch, I use ratchet wire tensioners for building building fence corners and H-braces, as well as for tensioning our solar-charged electric fences. I was recently bemoaning the fact that the only tensioners that I could find at my local feed store and hardware store were made in China, and priced at nearly $4 each. So I did some searching and found a mail order company called Zeitlow Distributing Company in McPherson, Kansas that specializes in electric fence products. They sell the Tru-Test Strainrite tensioners that are made in New Zealand. They had these sale priced at just $2.66 each. They also shipped my order very quickly--apparently shipped the same day. Note that the Strainrite ratchet tensioners (called "cliplock strainers", in Kiwi parlance) are slightly wider that the typical American ones (such as the old Hayes brand), so you will need a tensioning tool (aka "ratchet handle") made by Strainrite, or one that is of compatible width.
