+Fully customizable mount to be used with HomeRacker.
+It's intended for non-standard devices you want to mount on HomeRacker.
+Non-standard being devices which aren't originally meant to be mounted in 10 or 19" racks.
+Devices might be PSU's for Raspberry Pis or small smart switches like on these pictures:
