I bought this parallel straightedge in June. Today I was finally able to get a good tabletop board prepared and was ready to mount the tool to the board. What a disappointment to find that the hardware kit that came with this tool is junk. The pieces are plastic, and badly tooled. Specifically, parts G and H in the hardware kit - the clinch stud and the rear adjustment knob - and part E, the right rear connector, do not fit together properly. The hole in the cheap plastic part E that G and H are supposed to fit into is too small - the depth is too shallow, so the clinch stud does not seat in the hole properly. Thus the connector cannot be tightened securely to the board. So this $215 tool is currently unusable, and I will have to find a better hardware kit for this brand new tool just to use it, or make my own, which will cost me more time and money. Again, what a disappointment. I wanted this one because it's big enough for a 60 x 40" sheet. But without good hardware it's not worth much, is it?
