If you have ever tried to pull stock wire (field fence) around awkward corners or up and over a rise, you will know how difficult it is to stretch it evenly. With this tool you can stretch each wire in turn, quickly and easily and the problem of gathering the excess at the top and bottom is minimised. You can work one post at a time, pulling each panel really tight as you go along – even put a different tension on each wire according to the situation.
