All "High Rise" style desks (those with the Upper Slide Out Rack Bays above the table) can be ordered without those racks to provide a high vertical clearance of 16.75" between worksurface and the rolltop mechanism. Great for video monitors or mix consoles with tall meter bridges, etc. The Rolltop Custom at far left without the upper bays creates clearance for a monitor (monitor not included). A normal Rolltop Custom with its Upper SlideOut Bays installed is shown on the right for comparison.
