Keyboard shelf is reversible, allowing two options for mounting keyboards. A standard keyboard can be placed in the recessed side. The recess is 5° from horizontal and contains a knockout to allow the keyboard cord into the shelf interior. The flush side of the shelf provides a 12° mounting surface for membrane-type keyboards. Hole and grommet in rear surface of shelf provide keyboard cable access into the enclosure. Shelf has aluminium die-cast ends and an aluminium extrusion across the front edge to add styling detail and function as a palm rest for ergonomic keyboard orientation. Rear mounting surface is gasketed to maintain the UL and CSA integrity of the enclosure. Shelf is 14 gauge steel and finished with RAL 7035 textured light-grey polyester powder paint. Aluminium trim and die-cast sides are finished with RAL 9005 textured black polyester powder paint.
