"We used these clamps to re-engineer our model train club's banner stand for tool-free assembly. We had to drill the T connectors to screw them to 3/4" EMT, but once that was done we had a pipe that could slip down another pipe until the banner was taut and then be eaily clamped in position. Together with judicious use of gravity and the fact that 1/2" IMC fits snugly in 3/4" EMT, we now have a banner/stand assembly that by opening a few clamps can be disassembed into pipes with minimal "stuff" sticking sideways, so they can fit securely into a 50" mic stand bag." - Thomas
