Basic support rings...
...if the distance from the support rod are not critical in your work. All four rings have a different distance as measured from the support rod.

OK if alignment is not important to you.
When clamped to a vertical support rod, the ring is a few degrees askew, not level. The ring itself is also slightly warped; i.e. the ring is not in a plane. So it was not suitable for my purposes. The clamps have plastic tee handles, not plastic circular knobs as in the picture here.

Inadequate Quality Control
I was disappointed that the rings are not perpendicular to the mounting axis on two of the rings. They have a slanted plane, when mounted.

Plastic screw handle; but pleased just the same.
Has plastic handle for tightening screw onto stand. Time will tell if it holds up. I'm concerned about it getting hot from the Bunsen Burner. I am very pleased with the purchase.
