I'm so excited that my PRO 1" connectors arrived! I've had a project in mind for a while. I wanted to make a Solar Panel rack for my heavy glass 180W panels. The rack holds two panels (so I can still lift it). The rack folds up for storage. It is adjustable for different sun angles around the year. I 3D printed endcaps, but got everything else from Home Depot. I used metal pipe hanger tape to hold the panels. A 2-1/4" u-bolt clamps the angle adjustment. It's nice that the PRO connectors have a tap-screw hole. This way you can make rotating T connectors.
