Universal power supply mounting solution for almost any multi power supply unit you can imagine. Its one-size-fits-all design can be mounted underneath any new RockBoard pedalboard (except Duo 2.0). Due to the construction of the RockBoard's vertical support braces no holes have to be drilled into your pedalboard and it can easily be fixed with only one screw. Using the holes in the Tray's surface, you can either mount power supply units to it using screws or cable ties. Also because of its flat surface hook and loop tape or other adhesive tape can be used to fix your power supply to it.
