3U Eurorack Side Brackets_Aluminium

Eurorack side panels provide guidance for your rails to form a correctly sized 3U frame.  Therefore fixing the rails and modules inside your case will be very easy. By combining together a few frames you can create a case of any case size you need. Therefore our side cheeks are perfect hardware for any of your DIY eurorack modular synthesizers. Panels are designed to work with Doepfer-style mounting rails with lips.
The construction of the brackets is laser-cut aluminum in silver color.

Why aluminium side panels?

  • Aluminium side brackets are much stiffer than plastic ones. We recommend using aluminum side brackets for constructions where additional stiffness is a necessary factor – plastic cases, leather suitcases, etc.
  • Aluminium side brackets can be used with rails of any length. We especially advise using aluminum side brackets, with longer rails – over 126HP – for extra rigidity.


The assembly process of a 3U frame using these 3U Eurorack Side Brackets is very easy: Align the holes in the bracket with a mounting groove in the profile. The top edge of the side bracket has to match the top edge of the rail lip – if those two elements don’t align, flip the side bracket for 180° degrees.  Fix both elements together with self-tapping M5 bolts. To make sure that rails are properly spaced and prevent them from rotating during assembly – put any 3U module between the rails before tightening the bolts.


  • The listing price is per pair of 3U Eurorack Side Brackets
