3-Pronged Clamps
3-Pronged clamps are used to clamp glassware and apparatus to a ring stand. They are actually more versatile than versatile clamps, in that they can hold any shape and most sizes of glassware and they can turn in any direction. However, they cannot attach to the ring stands on their own; a clamp holder is needed. These are usually left attached to the clamp after use.
