The TrainTrack pedalboard mounting brackets are designed to pair any standard Radial direct box with a Pedaltrain® pedalboard, so you can easily mount your DI or line isolator under your pedalboard for a more streamlined setup. TrainTrack brackets come with all the hardware you need to securely mount your Radial product on either side of the pedalboard and use the screw holes that are already on the DI so you can easily remove it for standalone use in the future.
