This device allows 3U rack gear to be rack mounted and then swiveled out to a 15 degree or a 50 degree angle. This allows users to angle a control surface when they are using it, and retract it when it is not in use.
This system will work on any of the Behringer synths like Neutron, Wasp, Model D, K2, Pro 1, etc. These will also work on many other rackmount controllers that are less than 3.5" deep at the bottom, and less than 17" wide. This will not work on DW-8P units, as those are 17.75" wide.
