External Mount Luggage Style Wheels/Dolly?
 

I've seen it several times before. Where is everyone getting the collapsible handle and wheels, external mount (without cutting into corners) for speaker cabinets?

I've looked, but can't seem to come up with the one I've seen in the past.

Thanks!!!

Great! Thanks!

I know it's a different subject, but is there a thread on tilt back designs or options?
