The Humanscale 500 & 900 Keyboard Tray with 11'' Track is The Human Solution's preferred keyboard tray configuration for our standing desks with crossbars. Its short track and mechanism allow for maximum storage under your desk when not in use (though please note that you won't be able to store your keyboard completely underneath with this short-track configuration). And with your choice of a 500 ''Big Board'' platform large enough to type and mouse on the same surface, or a 900 board with a separate adjustable 8.5'' diameter high clip mousing platform, you can pick which platform works best for you. Humanscale keyboard trays are our sturdiest and most adjustable keyboard tray systems, and the Humanscale 500 & 900 Keyboard Tray with 11'' Track gives you the perfect configuration for any limited depth desk or sit-stand desk with a crossbar or support beam underneath.

|''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)
The 11'' track pre-configured Humanscale keyboard tray is available with your choice of a "Big Board" 500 keyboard platform or a smaller 900 platform with a separate 8.5" diameter high clip mouse platform. Both come with a shorter 11" track to mount the keyboard tray without interference from your desk's support beam underneath, as well as a shorter 5GSM mechanism that gives you 4" of height adjustment and 15° of tilt and allows for four more inches of storage under the desk than a standard mechanism. While the track length will not allow for you to fully store your tray under your desk, we find that most customers don't need to store the keyboard away when not in use.
This Humanscale 500 & 900 Keyboard Tray with 11'' Track mounts easily to the underside of your desk. For those with limited depth to their desk, or with a metal crossbar running across it, this option is the right choice. Just make sure you have 11'' of depth!
