Hey vangkrieg, you uploaded some pics of your rack in a thread one year ago. I am currently building an own rack containing a shure psm 300 and a shure glxd-4. May I ask you how you picked the two devices next to each other in just one rack unit? Did you just cut out the rack extension kit of the shure psm 300, screwed the two parts together and packed the glxd-4 beside without further fixation?
