Humanscale 500 & 550 White Keyboard Trays

item#: HUS919

Humanscale 500 & 550 White Keyboard Trays offer the classic features of Humanscale's 500 keyboard tray in a brilliant white color perfect for matching contemporary office decor. An extra large surface lets users who would prefer both items be on the same plane in their neutral reach zone to have a full-size keyboard and mouse on a single surface. A standard 6G mechanism is included to help provide height and depth adjustment as well as a negative tilt that reduces wrist pronation when used with the optional gel palm rest. Humanscale 500 and Humanscale 550 keyboard trays are also available in black and platinum finishes as well.

Lateral Slider

All Humanscale mechanisms pivot 360 degrees from the point where it is mounted to the track. Some users have a need for additional side-to-side adjustability. The lateral slider provides for eight extra inches of movement from right to left. This is a useful feature for someone at a large workstation that requires them to type facing different angles or monitors.

Track Length

The track mounts to the underside of your work surface. It directs and supports the Humanscale mechanism and keyboard tray as it slides forward and back. Standard length on most mechanisms is 21 5/8 inches. That length ensures that the keyboard tray can be completely stowed under your desk when not in use. Some mechanisms come standard with a shorter or longer track. Consult each description for that information, but all systems can be ordered with any track length.

Palm Rest

Humanscale's palm rests are available in multiple sizes and thicknesses.

Palm rest lengths available for this tray: 20'' with 7'' mouse palm rest, 20'', 19'' with 7'' or 5'' mouse palm rest (slim thickness only), 19'' (slim thickness only)

Select one of the foam or gel palm rest options for the 500 (27" wide) or 550 keyboard trays (25" wide total). For the 500 Big Board, you can select a split palm rest with one 20" section and one 7" long section, or a 20" palm rest for the 550 board. This feature comes in handy if a user doesn't want a palm rest in front of their mouse or keypad (pictured in main image above). All are covered with an easy to clean, silver synthetic leather.

For users with "slim" keyboards such as those made by Apple, a 19'' "slim" gel palm rest is available. Please note that this palm rest will not reach across the entire length of the tray, and will not fit flush against the keyboard tray corners like the 20'', 25'', and 27'' palm rests. The slim 19'' palm rests will sit roughly 5/8'' away from the closest corner when installed.

Professor Ergo's Thoughts:

A key component of any ergonomic workstation, Humanscale 500 & 550 White Keyboard Trays allow you to position your keyboard tray directly in your neutral zone, reducing stress on your shoulders and elbows. By placing the keyboard in your lap at approximately elbow height, arm extension is minimized, preventing shoulder strain. A 6G tilt-adjustable mechanism also lets you gently slope the keyboard away from you, straightening your wrists and allowing your fingers to "droop" onto the keyboard in a relaxed posture.
