How to keep potentiometer in place

I was wondering how I can keep my potentiometers in a project box, do I glue them, solder them or how do I do it? I know how to hook them up, but not how to position them. Like rapid LED did this.
How did they get the potentiometers to stay in the faceplate? Any help would be appreciated.

 

You should be able to place screws in the slots on each end of the faceplate and attach it to anything you want.

 

No, I mean how did they get the potentiometers to stay secure in the faceplate?

 

ask rapid, im sure they would know before any of us, seeing how they make it.

 

There isnt a nut of some sort to attach the POT to the faceplate? I am just guessing that is how it is attached. You wouldnt want it to be too permanent.....may have to replace sometime down the road. Do you have another picture of the inside of the faceplate where the POTs go?

 

Underneath the actual potentiometer knob, there is a nut that secures it to the faceplate.
