Synth & Eurorack Parts / DIY

Aluminum blank panels for use with eurorack synths. These 1.6mm thick panels feature a painted black side and a bare aluminum side. Simply flip the panel around to match your color scheme. Elongated holes are used for the mounting holes to ensure a proper fit in your rack. These low cost panels are great for filling gaps in your system or making DIY modules. Blank panels are also referred to as blind panels. Standard Eurorack panels have the same height of 128.5mm but the width varies and is measured in HP. HP is short for horizontal pitch. A single HP is 0.2” (5.08mm). The 2HP panel will measure 0.4” wide (10.16mm”) and the 20HP panel will measure 4.0” wide (101.6mm).
