Pinch-Bolt 1/2 in EMT Rail Parts Bin
A 90 x 60 x 50 mm open parts bin with a 45° V-roof hook that hangs over a 1/2 in EMT conduit rail (17.9 mm OD) above a bench. One M4 x 35 bolt goes through 4.5 mm holes in the bin's rear pillar and the flexing back leg and pinches the rail, so the bin can't rock forward when it's loaded and you can slide it anywhere along the rail. The rail needs at least 25 mm of wall standoff to clear the 3 mm back leg.
