Star Tech. com understands that the needs of a Server Room can vary greatly, and some configurations change around at the drop of a hat. That\'s why we\'ve developed the SLIDESHELFD, a black 2-in-1 slide-shelf / keyboard tray that helps you keep costs down and productivity up. The SLIDESHELFD can be used as a sturdy sliding shelf, or a pull out drawer. As your server cabinet needs change, the SLIDESHELFD changes to suit. Need to change the drawer holding your keyboard or other input devices? Simply flip the installed drawer over and it becomes a shelf to hold monitors, laptops and other diagnostic equipment. An easy-to-hide handle pulls out to help you get a grip on the situation and hides away quickly. Comes with all the tools you need to install it in your server cabinet: rails, cage nuts, screws, ball bearing slide and adjustable brackets. This product is compatible with the 7236CABINET, RK2236BKF, RK4236BK, and RK4236BKNS Dura Rak cabinets.
