Ring Stand Holder for 20KHz Ultrasonic Stacks

This anodized aluminum holder clamps to almost any ring stand and securely holds an ultrasonic stack using a booster having a mounting ring with a diameter of between 2.65" (67 mm) and 3.25" (83 mm), which is most of the standard ones.

To mount a stack, set the holder to an appropriate height on the ring stand and simply hang the stack in the holder.

Not using a booster? Flip the holder over and use the other side, which is a better fit for converters with diameters between 2.65" (67 mm) and 2.99" (76 mm) which includes almost all 20KHz converters of at least 500 watt power capability.

Need more security than gravity alone can provide? While this model does not include them, booster retention blocks and hardware are included with model RS200B, and a pair of blocks and hardware may be ordered separately to add to this model (after you try it out without) as model RS200B2.

If you are using a booster in the stack, you should probably consider using two of these holders, one for the booster and one for the converter/transducer. It is possible that the reactor vessel you are using would be a good fit in this holder as well.

Made in USA of aircraft grade aluminum anodized and nickel sealed, and includes nickel-plated steel thumbscrew.
