Humanscale 300 Curved Keyboard Tray Platform System

Description

We offer a full line of durable keyboard and mouse platform options created to meet the needs of a wide variety of individuals, workstations and office environments. Each of our platform options is designed to ensure that users type and mouse within their Neutral Reach Zone, thereby encouraging safe, sustainable working postures.

By combining one of these platform options with one of our award-winning mechanisms, you will create the most non-intrusive, intuitively adjustable keyboard support available. All of our keyboard and mouse platforms are made of phenolic, an ultra-strong, remarkably thin (1/4") composite that`s non-toxic, durable and easy to clean.

Humanscale 300 Curved Keyboard Platform: This platform supports most "ergonomic" keyboards, such as the Microsoft Natural Keyboard, and is compatible with any of our mouse platform options. Dimensions: 20-3/4" W x 9-1/2" D.

Keyboard Systems - In many ways, a keyboard support is the heart of an ergonomic workstation. As reach and vision drive posture, an articulating keyboard system allows the user to sit in a healthy, neutral posture through bringing the keyboard and mouse to the user. A well-designed articulating keyboard system offers protection from carpal tunnel syndrome, neck and back pain and other musculoskeletal issues. Since 1995, Humanscale has been the leading manufacturer of articulating keyboard systems and today sells more than all other manufacturers combined.

Effortless Use - Humanscale patented keyboard systems have effortless height and angle adjustment. Promoting negative tilt keying, the keyboard platforms will not go into a positive tilt.

Durability - Humanscale keyboard trays are solidly anchored to any work surface, and shape to specific user needs. Hypoallergenic Gel palm supports offer height and durability, and are designed to be compatible with human skin.

Customization - Humanscale offers three negative-tilt keyboard systems, from 5G to our latest 6G, which combines easy dial-a-tilt and height adjustability with the strongest, most stable arm on the market. Humanscale keyboard supports come in many different configurations, including left/right customization, to support any user need.

Design Story - An ergonomically designed keyboard is essential for every workstation. Ergonomists agree that the healthiest typing posture is one that allows the wrists to maintain a neutral or slightly pronated posture - straight or bent at a slightly downward angle. For that reason, Humanscale designers created our keyboard systems to allow the keyboard to positioned anywhere from 0 degrees to a -15 degree angle.

A decade of ergonomic research shows that using a negative sloped adjustable keyboard tray maximizes the time spent working in a neutral hand, wrist and upper body postures. These postural benefits can’t be achieved by just using a keyboard on a height-adjustable work surface." - Dr. Alan Hedge, Cornell University

The Neutral Reach Zone

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)

Unlike older generation keyboard/mouse solutions, our platforms are designed to ensure that nearly all users are able to work consistently within their Neutral Reach Zone, and thus maintain a low-risk, sustainable posture.

Neutral Reach Zone

Option 1 - Color

Black

Option 2 - Arms Type

5GSM

5GAD

Option 3 - Track

Refers to the under-desk mounted track that the mechanism slides along. Measure the amount of flat space you have on the under-side (from front to back of your desk) to determine which track length best suits you. The longer the track you are able to fit, the farther underneath the desk you will be able to slide the platform. The track measures 5-1/2" in width and is available in seven lengths:

11" Track	For real small Desks at least 11" deep "from front to back"
14" Track	For real small Desks at least 14" deep "from front to back"
16" Track	For real small Desks at least 16" deep "from front to back"
18" Track	For smaller Desks at least 18" deep "measure from front to back"
21 3/4" Track (Standard)	For use with 22" deep Desks "measure from front to back"
25" Track	For deeper Desks with up to 25" depth "from front to back"
27" Track	For real deep Desks with up to 27" depth "from front to back"

Option 4 - Track Length

Desk has more than 22" clear space under desktop, front to back
Less than 22" & more than 18" clearance under desktop, front to back
Less than 18" & more than 16" clearance under desktop, front to back
Desk has less than 16" & more than 14" clear space under desktop, front to back

Option 5 - Mousing Platform

Clip Mouse - The only mousing platform that lets users adjust their mousing position in all three dimensions for maximum comfort. With height, depth, lateral and tilt adjustability, it can be positioned where it is needed for truly custom support. It can also be easily moved from one side of the keyboard to the other for left- or right-handed use.

Height - Clip Mouse platforms model 90 and 91 can be in one of the two positions. Position one is parallel and to the side of the keyboard. Second position is approximately 1.5" above and over numeric keypad/keyboard.

Clip mouse adds minimum of 4" to maximum of 10" to either side of the keyboard platform. Clip mouse is not recommended for In small and tight areas areas such as small cubicles.

8.5"	Clip Mouse (for right or left hand)	90
8.5"	Clip Mouse (dual for both hands)	90D
8.5"	High Clip (for right or left hand)	90H
8.5"	High Clip (dual for both hands)	90HD
10"	Clip Mouse (for right or left hand)	91
10"	Clip Mouse (dual for both hands)	91D
10"	High Clip (for right or left hand)	91H
