Humanscale Keyboard Mechanisms

Building a Humanscale keyboard system starts with finding the right mechanism for your setup. The mechanism determines the height adjustment and negative tilt for your keyboard tray.

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.

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

5G mechanism

The dial-a-tilt mechanism instantly adjusts the platform's tilt without the need to lock or loosen any knobs or levers. Its solid build quality and simplicity make this mechanism the most popular mechanism Humanscale offers.

Height adjustment 6.25": 1.25" above track to 5" below track
Track length Comes standard with 22" 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.

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

5GAD mechanism for above-desk use

This mechanism's greater-than-average adjustment range is ideal for sit-to-stand workstations, featuring steel construction for stable keying and mousing.

Height adjustment 13.5": 7.5" above track to 6" below track
Track length Comes standard with 27" track

4G mechanism

This is the older version of the 5G mechanism, featuring dial-a-tilt keyboard angle adjustablity.

Height adjustment 6.25": 1.25" above track to 5" below track
Track length Comes standard with 22" track

4GAD mechanism for above-desk use

This is a version of the 4G with a longer arm for use above a work surface, making it great for sit-to-stand soulutions.

Height adjustment 11.5": 8.5" above track to 3" below track
Track length Comes standard with 27" track

2G mechanism

Loosen knob to adjust and lock back into place. Unlike the 5G or 6G, this mechanism has no reference for keyboard platform angle.

Height adjustment 6.25": 1.25" above track to 5" below track
Track length Comes standard with 22" track

KM mechanism

This mechanism features a pre-set 0 degree tilt and knob-free adjustment.

Height adjustment 6.25": 1.25" above track to 5" below track
Track length Comes standard with 22" track
 

Lateral Slider

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.

 

Mouse Platform

A separate mouse platform is not available with the Humanscale 550 Big Compact Keyboard Tray as this keyboard tray is large enough to support mousing on the main platform.

Palm Support

For the Humanscale 550 Big Compact Keyboard Tray, you can select a solid 25" palm rest or a split palm rest with one 20" section and one 5" long section; this feature comes in handy if a user doesn't want a palm rest in front of their mouse or keypad (pictured in main image above). All are covered with an easy to clean, black synthetic leather.


For users with "slim" keyboards such as those made by Apple, a 19'' "slim" gel palm rest is available. Please note that this palm rest will not reach across the entire length of the tray, and will not fit flush against the keyboard tray corners like the 20'', and 25"' palm rests. The slim 19'' palm rests will sit roughly 5/8'' away from the closest corner when installed.

 

Humanscale Palm Rests

When designing your Humanscale 550 Big Compact Keyboard Tray, if you choose to not add a palm support, there will be holes located at the installation points on the tray.


This is normal and part of the keyboard tray's design, but if you do not want a palm rest and installation holes in your tray, we suggest ordering another keyboard tray.


If you have any questions or need help choosing a keyboard tray, please don't hesitate to call us!

 

Track Length

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.

 

Mouse Pad

A mouse pad for the separate mouse platform is not available with the Humanscale 550 Big Compact Keyboard Tray as this keyboard tray is large enough to support mousing on the main platform.

 

Second Mouse Pad

A mouse pad for the separate mouse platform is not available with the Humanscale 550 Big Compact Keyboard Tray as this keyboard tray is large enough to support mousing on the main platform.

    It gets the job done, but a few complaints.

    Posted by Taylor on Jun 23rd 2017

    This keyboard tray is a great size, fits both my keyboard, my rollerbar mouse and my regular mouse. The tray is very thin, 1/2 a centimeter thick. I wish it had a locking feature to lock it at a specific height because when I hit it with my knee, it moves up and I have to readjust it again. It is very slow moving in and out from under my desk, have to push pretty hard to get in under the desk all the way.

This product comes standard with a 15-year warranty.
