I struggled a bit installing a Furman Power Conditioner/Surge protector and a Soundcraft Ui16 into this rack.  The installation requires that you install your rack mounted devices in between the case and a supplied rod and then use the bolts to make the connections through 3 consecutive holes for each bolt that your device requires. It got a bit tricky because the rod does not easily line up with the holes on the case and holes on my devices, so it took some doing.  However, once done, it appears to offer solid connections and device security.  So overall, I would say it was worth the installation effort.
