“Although this spooler DOES tighten the fence well, it is very difficult to use unless you purchase the pricey ($100+) spooler tool. Without the tool, it took two of use to tighten each spooler - one tightening from the bottom and one from the top. Second issue is that the one has to be very careful to turn the top and bottom equally at the same time, or the fence tightens with a twist. Third issue is that one spooler was shipped damaged where there was a week point in the spooler which caused the part where a tightener tool is inserted to twist and break. I have not notified Kencove yet, and do not anticipate any issue in getting a replacement.”
