How It Works
– The knob is tilted slightly and then slid down over the
– threaded spindle. (see drawings at right **)
– When in position, the knob is brought into a straight
– position … mating the two threaded segments within
– the knob to the threads on the spindle.
– The knob is then turned clockwise until snug … just
– 1-1/2 to 1-3/4 turns.

Which Size Do I Need?
Due to the huge number of available vibratory polishers, it is impossible to list the thread sizes of each of them. So the best way of determining the QR Knob size you need is to measure the spindle. There are two ways that work.
1) Test fit a hex nut of know size onto the spindle or test fit the wing nut onto a bolt of known size.
2) Measure the spindle diameter using your calipers.
2) 1/4″-20 = .2489″ to .2408″
2) 5/16″-18 = .3113″ to .3026″
2) 3/8″-16 = .3737″ to .3643″
| † Spindle must extend at least 3/4″ above cover of case cleaner for this Quick-Release knob to work. ** Line drawings are for instructional purposes only and are not identical to actual product. Case cleaner shown in photo and video is not included. |
