This ring support works very well. It is easy to attach to a ring stand (I use a pair of pliers to help secure it to the stand). If you put the wire gauze on top, it easily supports beakers, flasks etc. Another great thing about it is can support most funnels too.
It works well
It's well made and solid. The screw threads are smooth. It does what it was made to do.
This ring is designed to support beakers, flasks, etc. on a ring stand. Don't forget to order wire gauze or a clay triangle if needed. The sturdy steel ring and aluminum clamp have a durable black powder-coated finish.
Note: The coating is heat resistant to 350°F and is not for use in direct flame.
