Humanscale 500 Big Board Keyboard Tray System

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 Keyboard Tray

• 500 board offers the widest single surface for a keyboard tray
• 500 Big Board keyboard platform is made of phenolic: it's an ultra-strong, remarkably thin (1/4") composite that's non-toxic, durable and easy to clean
• Humanscale keyboard trays are the highest quality on the market
• The Humanscale 500 keyboard tray platform design supports a variety of keyboards and mice combos and will fit most desks using the variety of tracks lengths available; see the Options tab for more details.
• No mouse platforms come with these boards since the worksurface is so large; users would reach too far for a mouse outside their neutral reach zone

Neutral Reach Zone Description

"The neutral reach zone is the area that can be conveniently reached with a sweep of the forearm while the upper arm hangs in a natural position at the side. (Sanders & McCormick, 1993)

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.

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.
