Document Camera Drawers (DCD) come a varying sizes depending on the size of the lectern and the document camera(s). They are installed on either the left or right side of the lectern. If the lectern is large enough, they can be installed on both sides at the same time. They come standard as locking drawers.
Document Camera Drawers often compete for space with equipment racks and storage in the lower compartment of the lectern. In most lecterns, a DCD limits you to ten rack units of equipment space.
