Although I have plenty of pipe clamps in various lengths, there have been times when I needed more reach. Yes, I know that you can attach pipe couplers to the tail end of a pipe to extend it, but that’s too much hassle. There’s a much quicker and easier way.
I just select two clamps of appropriate length and rotate their jaws to interlock as shown. While this isn’t necessarily the best approach for edge-gluing panels, it works great for assembling very wide cabinets, attaching edging from a distance, and other long-reach clamping chores.
