The mechanism is the arm that controls the in-and-out movement, the height range and the tilt angle of your keyboard platform. All of the Humanscale keyboard tray mechanisms offer independent height and tilt adjustment with varying levels of height adjustment and standard track lengths. The 6G and 5G mechanisms are the most popular and suit a variety of workstation needs; they are strong and durable, easy to use and offer a good range of motion. The 6G is the newest Humanscale keyboard tray mechanism that offers a more streamlined design than the 5G. The 5GSM offers the same functionality as the first two but for limited depth desks. The rest of the mechanisms offer special features, like the AD for above desk applications or the DS for users who need two point of adjustment for facing different directions.

Humanscale KM Keyboard Tray Mechanism without Tilt Adjustment
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.
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.
Clip Mouse - Mousing Platform
The clip mouse platform is the only mouse platform that allows the user total adjustment control in all three dimensions- height, depth, forward/back and tilt, allowing it to be adjusted precisely the way you need it. It also easily snaps onto either side of the tray for left or right use, and it's available in two sizes and different height ranges. The high clip has an extra one inch height for additional adjustment and usability and is the most popular accessory we sell.

- 91H: 10" diameter high
- 90H90H: 8.5" diameter high - Dual platforms for left and right
- 91H91H: 10" diameter high - Dual platforms for left and right
Swivel Mouse - Mousing Platform
The swivel mouse mounts underneath either the left or right front corner of the platform. It swivels out from underneath the keyboard platform easily and tucks out of the way when not in use. This mouse platform is available in right, left and dual configurations. The main difference between the clip mouse and swivel mouse is the adjustability. The swivel platform stays on the same tilt or angle as the keyboard tray; the clip mouse angle can be adjusted independently.

- 11L: 8" swivel left
- 11D: 8" swivel dual

M2 Mouse - Mousing Platform
The M2 offers all the advantages of the swivel mouse, but it is slightly larger and offers a uniquely shaped platform. This lets a user bring the mousing surface closer to their body for a lower risk mousing position.

- 81L: M2 left
- 81D: M2 dual

The Humanscale 300 Curved Keyboard Tray design ensures that users type and mouse within their neutral reach zone, creating a safe, comfortable and sustainable work environment. The neutral zone in a standard office workspace is defined as the area where a user sits and works at a desk and can easily reach and interact with surrounding computer accessories, including a keyboard and mouse. Unlike older generation keyboard and mouse solutions, Humanscale keyboard trays are designed to ensure that nearly all users are able to work consistently within their Neutral Reach Zone, and thus maintain a low-risk posture. This Humanscale keyboard tray platform is not available with a palm support.
