The Heavyweight Champ of Pipe-Clamp Rocks
By building this pipe-clamp rack (it takes no time at all), you can store dozens of clamps in a small space. You'll need some 2x4 stock, 1⁄2 " steel rod, 31⁄2 " lag screws, and washers. Drill 1⁄2 " holes at a 5° upward angle through the 2x4 where shown. Then, attach the 2x4 to your wall with the lag screws. Cut your steel rod and chamfer the ends (for safety) with a file or bench grinder. Drive the rods into the holes in the 2x4 and hang your clamps.
