This unit attaches to the underside of a desktop surface or keyboard tray, and can easily be stored when not in use. The keyboard area is foam covered and 21.75" x 10.5" (55.2 cm x 26.7 cm), and provides ample room for ergonomic keyboards or conventional keyboards and gel supports. The mouse platform is top-mounted and swivels over the 10-key pad. It is a right-hand mount (left hand mount available by special order). The useable mouse area is 9.5" x 8" (24.1 cm x 20.3 cm). A 1" (2.5 cm) keyguard helps protect your keyboard and assist in cable management. The unit is composed of a metal mounting bracket with a vinyl-coated MDF board.

If you have an arm already, compare this Hole Pattern to see if this tray can be fitted to your arm.

The Heavy Duty Melamine Corner Keyboard Platform from WorkRite Ergonomics is a rigid platform designed for installation in the inside corner of most L-shaped desks. The rear corners are cut at a diagonal to permit the mounted tray to be elevated level with or above the desk surface. The large 27.75" W x 11.75" D platform is constructed of 5/8" thick melamine and edged with durable PVC trim. The additional thickness of this platform offers a rigidity that other thinner surfaces cannot provide and the greater mass aids in reducing vibration that can occur with lighter trays.

The Corner Keyboard Platform is equipped with soft leatherette over foam mouse and keyboard palm supports. The interchangeable mouse and keyboard sections can be easily removed if not desired, or interchanged for left or right-handed mousing. The convenient mouse cord clip can also be moved to the desired side.With the palm rests installed there is still about 8.75" of depth available for the keyboard. When the palm rest is removed that depth increases to the full 11.75".
NOTE: This platform can be mounted on the Ovation Low Profile Leverless Arm or the Ovation Sit-Stand Keyboard Arm.
