3U Eurorack Aluminium Side Brackets – DIY Modular Synth Accessory

Build a precise and sturdy 3U Eurorack frame with our high-quality aluminium side brackets. Designed for Doepfer-style Eurorack rails with lips, these side panels guide your rails for a correctly sized frame, making it easy to install rails and modules in your DIY Eurorack modular synthesizer. Combine multiple frames to create custom Eurorack case sizes effortlessly.

Why Choose Aluminium Side Brackets?

Aluminium side brackets are far stiffer than plastic alternatives, providing extra rigidity for DIY Eurorack cases—especially plastic cases, leather suitcases, or longer rails over 126HP. Their durable 3mm thick laser-cut aluminum construction is anodized silver for a sleek finish and long-lasting performance.

Easy Assembly for DIY Eurorack Frames

Align bracket holes with the mounting grooves in your Eurorack rails.
Ensure the top edge of the bracket aligns with the rail lip—flip it 180° if necessary.
Secure with self-tapping M5 bolts.
Place any 3U module between the rails to maintain spacing and prevent rotation while tightening.

There are no longer any shims to prevent the aluminium profiles from pivoting.
