Yes, the “KW” series of shelves do have an integrated writing surface along with a keyboard tray underneath the shelf. The “KW” series can be 18″ deep to 36″ deep, but the most common is the kw30 series. For all “KW” series the total shelf depth is 6″ more than the basic shelf depth because the writing surface extends past (overhangs) the shelf by 6″. The writing surface is a total of 18″ deep so it also extends back over the shelf by 12″. The “KW” series is available with a single keyboard tray in lengths of 30″ to 36″ and with two keyboard trays in lengths of 60″ and 72″. For longer lengths, multiples of the above are used.
