Humanscale Keyboard Mechanisms

6G mechanism

Humanscale's newest dial-a-tilt mechanism that instantly adjusts the platform's tilt without the need to lock or loosen any knobs or levers and slimmer than the 5G. The 6G mechanism is available in black or white.

Height adjustment 7": 1.75" above track to 5.25" below track
Track length Comes standard with 22" track

6F mechanism

This mechanism is specifically meant for users with a height adjustable desk, such as the Humanscale Float. The short track allows for full retraction of the keyboard tray underneath the desk. Height adjustment is made by repositioning the entire desk to bring the keyboard tray to a proper working level. This mechanism is available in black or white.

Height adjustment No height adjustment capabilities
Track length Comes standard with 12.5'' track

5GSM mechanism for limited-depth desks

This mechanism goes 4" farther underneath a desk surface, getting a keyboard tray stored out of the way on a shorter track, perfect for desks with limited depth or small spaces. This mechanism is available in black or platinum.

Height adjustment 4": 0.5" above track to 3.5" below track
Track length Comes standard with 18" track

Humanscale Keyboard Mechanisms

Lateral Slider Option

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 Options

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.
