item#: HUS067

The Humanscale 900 Dual Mouse Platform Keyboard Tray gives you an extra mousing surface versus a Humanscale 900 Keyboard Tray Standard System. Using this second platform, the user can setup a dual mouse configuration. This configuration would also support a numeric keypad and mouse, or provide a unique setup to share the keyboard tray system with someone who mouses with an opposite hand. The Humanscale swivel mouse platforms rotate easily out of the way when not in use, freeing up space.

Humanscale 900 Dual Mouse Platform Keyboard Trays position the keyboard and mouse within the user's neutral reach zone. Ergonomic keyboard trays help maintain correct ergonomic positioning to eliminate much of the repeated stress that comes from holding arms and hands in improper positions for long periods of time. They provide convenient movable surfaces for mice and keyboards. Individuals desiring articulating surfaces that independently adjust and tilt at a different angle than the keyboard platform are advised to use a Humanscale 900 Standard Keyboard Tray - Design Your Own with a dual clip mouse platform.

Professor Ergo's Thoughts:

A keyboard tray is a key component of an ergonomic workstation. Position your keyboard tray so you can type and mouse while keeping your wrists straight. The ideal height for the keyboard is at elbow height or lower. Typically you should locate the keyboard tray just above your lap height. Your upper arms should hang comfortably at your sides as you work. The keyboard tray should be gently sloped or tilted away from the user to allow the wrists to be straight instead of flexed. When properly adjusted, a keyboard tray allows the back, neck, shoulders, and wrists to relax. The size of the keyboard tray must accommodate the keyboard and any input device like a mouse. Avoid having your keyboard on a tray and your mouse on the desk.

Additionally, be sure to measure under your desk to make sure the track will fit from front to back. It's better to have a slightly shorter track than one that is too long. If you have any questions or need additional information, please don't hesitate to contact us via email or by phone.
