This studio equipment rack stand with casters is perfect for today’s modern musician. While the all-steel construction is sturdy and durable on this dj rack cart also flexible with a top mixer platform mount that should easily hold any audio mixer or unit that measures up to 36 wide by 27 long by 3 deep. The bottom rackmount features 9 vertical space mounts and the top platform rackmount supplies 10 space mounts. This can also accommodate mixers that are over-sized for a standard rackmount case and/or not rack-mountable. Two included padding strips may be applied to the top 10 space mounting platform to hold the mixer or unit and the metal lip located at the end of each arm on the top platform will keep the mixer from sliding down. The maximum recommended mixer size is 36 wide by 27 long by 3 deep. The knobs on each side of the top platform will allow the user to adjust the angle of the top rack-mountable mixer platform; it can be adjusted to a level surface or to a slanted angle for easier visibility. Two of the four heavy-duty steel casters feature a lockable option to hold the stand in place.
