Mechanism - Humanscale 500 Keyboard Tray

Choose between Humanscale's three most popular arms.

The 5G and 6G mechanisms are their newest and most user-friendly mechanisms. They are built for maximum stability and are extremely durable. They feature:

  • Easy, knob-free height adjustment
  • Dial-a-tilt platform allows you to set a negative tilt from 0° to -15° , accommodating the negative tilt highly recommended by most ergonomists for safe keyboarding
  • 360° swivel
  • Platform stows completely underneath the work surface with the standard 22" track

The 2G mechanism offers the same range of adjustment but the tilt is not as easy to set. This is a great choice if you're seeking to save some money without sacrificing quality or function.

2G Specifications

Height adjustment 6.25": 1.25" above track to 5" below track

Track Length

The track mounts to the underside of your work surface and is what the mechanism slides forward and back on. Standard length on this mechanism is 21 5/8". If you do not have enough depth under your work surface to clear this, please see our Humanscale 500 & 550 Big Keyboard Tray - Design Your Own listing. Be sure to measure the depth under your desk (front to back) to confirm the track will fit; you need to have a track at least 1/2" shorter than the overall depth of your desk.

The Humanscale 500 Big 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. These boards keep everything on one worksurface rather than use a mousing platform; this keeps a mouse on the same tilt as a keyboard in use.

If you prefer to set the mousing surface angle separately, any of the other Humanscale keyboard trays aside from the 400 keyboard tray platform offer this option.

Features - Humanscale 500 Big Board Keyboard Tray - Standard Configuration

  • Humanscale 500 board offers the widest single surface for a keyboard tray
  • Platform features phenolic construction - ultra-strong, remarkably thin (1/4") composite that's non-toxic, durable and easy to clean
  • Design supports a variety of keyboards and mouse combos and will fit most desks using the variety of tracks lengths available; see Options tab for more details
  • Integral mouse surfaces provide mousing space for both left and right handed users

Solid keyboard tray
January 21, 2014
This tray is generously sized (the biggest I can fit under my 30" desk!) and well built. I feel like it will last for years with proper care. I would definitely recommend it to others. Just two small quibbles: 1.) The mechanism does tend to drift upward a little as I slide the tray in and out from under my desk. It would be great if it were possible to fix or lock the tray position semi-permanently. 2.) I chose not to buy a wrist rest, and the exposed mounting holes for that are kind of unattractive.

Humanscale big keyboard
November 3, 2010
Great product, extremely robust and will last a lifetime. Comparable to Anthro or other commercial rated office furniture. Since I'm very short, this is one of the very few keyboard tray systems that actually tilts to my level which is shorter than average. All of my wrist problems have ceased the day I started using it! No joke. This product does need a little assembling, and I had to ask a friend to install for me, because it is heavy duty material and was too heavy for me to wrangle myself. I highly recommend without reservation.
