I built this monitor stand for a conference last fall. It was used to hold a 50-inch TV vertically. It features a couple of interesting innovations and has several requirements. It must be portable for transport, solo assembly, assembly on-site, it had to roll, and it had to fit through standard doors after assembly.

I wanted the mount to be stronger than an off-the-shelf wall-mount bracket, 2x6 lumber metric bolts held the TV to this frame perfectly.

The casters I used had threaded stems and were attached to T-connectors. Several nuts threaded onto the stems fit inside the T-connectors to prevent movement, and a large washer and nut on top made the caster and T-connector one strong unit. Those T-connectors had screws driven into the EMT to keep the casters vertical.

The frame base geometry was a good compromise of width for stability and size to fit into tight places. The frame was incredibly strong. During design, I could stand on it so I was confident that a 50lb TV was no problem.

The geometry of the connections around the back casters and top of the assembly was a bit tricky as I was adding compound angles that the hinge connectors handled well. This made assembly a little tight, yet once everything was torqued down, it held together very well. I used a ratchet wrench with a hex socket for more torque and extra holding power. The connectors handled this with no issues.
