1U 6HP Blank Panel Tile
Easily mount your DIY Eurorack project to our 1U high-quality fibreglass blank panels. You may also want to cover up a glaring blank spot, and at the same time, promote your favorite synthesizer company; but if not, just flip the panel around for a blank black logo-less surface.
Fibreglass proves to be rigid yet easy to drill through. Please make sure to use ventilation and respiratory protection needed when drilling fibreglass.
