BP-3U-4HP
Easily mount your DIY Eurorack project to our 3U high-quality fibreglass blank panels. You may also want to cover up a glaring blank spot, and at the same time, promote your favourite 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.
This is a 4HP panel. Please look at the related products for other sizes.
These merchants probably sell this module. Huh?
