THE NEUTRAL REACH ZONE
The Neutral Reach Zone is the area that can be conveniently reached with a sweep of the forearm while the upper arm hangs in a natural position at the side.” (Sanders & McCormick, 1993)
Unlike older generation keyboard/mouse solutions, our platforms are designed to ensure that nearly all users are able to work consistently within their Neutral Reach Zone, and thus maintain a low-risk, sustainable posture.
Installation Information:
All keyboard platforms need adjustable arm installed under the desktop or table. In order to install adjustable arm with standard track, the desk or table must be at least 22." deep. The undersurface must be flat and free of drawers, structural supports and other obstructions. A 22" track will be directly mounted to the underside of the desk or table with ten 3/4" screws, so the undersurface must be able to accept wood screws.
You might install a shorter track (18" or 16" ) If your desk is less than 22" deep. In that case your keyboard tray might not retrieve all the way under the desktop.
An arm with shorter track (18" or 16") is capable of handling all ergonomic functions such as bringing the keyboard tray up or down, in and out, swivel to left and right and provide negative tilt.
