Humanscale 100 Combo Keyboard Tray System

The Humanscale 100 Combo 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.

Mechanism

Choose between Humanscale's three most popular arms.

The 5G and 6G mechanisms are Humanscale's finest keyboard tray mechanisms and are built for maximum stability and to be extremely durable. They feature:

• Easy, knob-free height adjustment with a range of 5" below the work surface to 1 1/4" above the work surface
• 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 6G is the newest mechanism that is slimmer and uses less material for production than the 5G

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.

Track Length

The track mounts to the underside of your work surface, and it 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 100 Combo Keyboard Tray - Design Your Own listing. Be sure to measure the depth under your desk (front to back) to confirm the track will fit; it's best to have a slightly shorter track than the overall depth of your desk.

Mouse Platform

Choose between either the 8 1/2" high clip mouse or the 10" diameter high clip mouse. The clip mouse is their most popular mousing platform since it is the most versatile, allowing you to slide the platform forward or back, swivel it over your keyboard/numeric pad, adjust the tilt or switch from the right to left side of the keyboard platform without the need for tools.

Allowing the mousing platform to swivel over the numeric pad area on your keyboard allows you to move your mouse closer to your body and into the neutral zone which is healthiest for mousing and reducing the stress on your shoulders. Most users will be happy with the 8 1/2" diameter mouse platform, however a 10" diameter is available for those who need a larger surface.
