1U eurorack side cheeks (intellijel format) provide a guide for your rails and will form a correctly sized 1U frame, making it easier to fix and correctly position your rails.
The cheeks are made from anodised aluminium and are 3mm in depth (please note that these are 0.2mm thinner than the 3U cheeks). There are three holes, which are used to attach the rails to the cheek, taking M5 Bolts and the smaller inner holes for attaching the cheeks to your case. The holes are all countersunk, allowing you to attach the frame to the case and the rails without affecting the modules. You will need flat head screws with the cheeks to work when attaching your case and modules.
These work with the Eurorack Mounting Rails we supply, which are available in 84HP to 168HP and customisable to your specifications.
NOTE: These cheeks do not work with the Vector Rails.
