Cazlangtvy 4Pcs Aluminum Alloy Silver 25mm Round Pipe Connector Right Angle Tee, Frame Display Stand Assembly Combination Drying Rack Connection Fastening Joint

Quite light and strong. The company has 1-way side connector and 2-way corner connector. Both are great. It is possible to assembly 4-way cross connector from 4 corner elements. So you can add cross to your assortiment. If you add just one new element for 2-way straight connector, then you can sell it and 3-way tee connector. Then you will have all possible stand connectors and be the only company providing full assortment of stand connectors. Good luck!

I built a project with 3/4 conduit, nominal diameter of 1" which fits these clamps and one clamp broke collapsing the whole thing to the ground. Weak. Cause of failure was two guy lines on one side pulled out of the ground despite one a piece of rebar rod a full foot driven into the ground. I still don't recommend using 3/4" conduit for outdoor projects and anything that is semi-permanent should be anchored with a concrete pour with eye bolts installed in the concrete to fasten guy lines to. You need some body around the thin rebar rod to fasten to the ground so the concrete is ideal. It doesn't have to be too much and can be level with the ground so can mow around it.
