| Product Summary |
|---|
The Diagonal Big Board Keyboard Tray from Humanscale is designed to be used at corner workstations where the tray needs to be elevated level with or above the desk height. The angled edges at the rear enable the tray to fully clear the edges of the desk when the tray is extended. At 27.5" wide and 11.5" deep, the Diagonal Big Board Tray provides plenty of space for both the keyboard and the mouse. Its symmetrical design allows the mouse to be used comfortably on both the left and right sides. The tray is composed of phenolic, an ultra-strong, remarkably thin (0.25") composite that is non-toxic, durable and easy to clean.
Note: The Diagonal Big Board Keyboard Tray can be mounted to the Ovation Low Profile Leverless Arm from Fox Bay Industries. |
| Ergonomic Benefits |
|---|
Positions Keyboard and Mouse within the "Comfort Zone" - Keeping frequently used devices within the Comfort Zone allows the muscles of the upper body to remain relaxed and reduces the risk of overreach (left and right, up and down, and forward) injuries. Learn More About the Comfort Zone.- Reduces Excessive Reach to the Left and Right - The Diagonal Big Board Keyboard Tray allows users to position both input devices comfortably close to the body and at the same level relative to each other.
- Keeps the Shoulders Level - By allowing users to keep both input devices on the same level, the Diagonal Big Board Keyboard Tray eliminates the need to repeatedly lift, extend and lower the shoulder when using the mouse. Dealing with a constant shoulder imbalance leads to an increased risk of repetitive strain injury. (Note that trays with a pivoting mousing surface can also raise or lower the mouse below the level of the keyboard and therefore carry the same potential risk.)
- Reduces Forward Reach - By positioning the mouse directly adjacent to the keyboard there is no need to reach forward to the desk surface—a common practice that creates a twist in the back and shoulders.
Allows Obstruction-Free Negative Inclination - With a thickness of only 0.25" the Diagonal Big Board Keyboard Tray offers individuasl maximum freedom to create a negative inclination for the keyboard without obstructing the legs. A negative inclination creates the neutral wrist alignment known to combat the development of Carpal Tunnel Syndrome. Learn more about Carpal Tunnel Syndrome.
Uniform Height - The entire tray surface is at the same height - meaning that workers are not reaching up and down to access their mouse. The single height assists them in positioning both keyboard and mouse for optimal ergonomics, reducing the risks of developing potentially disabling conditions such as Carpal Tunnel Syndrome.

| Features |

- Designed for Corner Installations: Unlike most keyboard trays the Diagonal Big Board Keyboard tray is not a standard rectangle. This tray is designed for deployment in corner installations so the rear corners of the tray are cut at a diagonal which permits the tray to stay clear of the desk should it need to be raised level with or above the mounting surface.
- Ample Space: At 11.5" deep this tray will accommodate most standard keyboard and central pointing device combinations. The 27" width offers sufficient space to support both keyboard and mousing devices of all styles. While some space is lost due to the rear diagonal cut corners, this does not really affect mouse usage.
- Integrated Mousing Surfaces: A low friction mousing surface is adhered to both left and right sides of the keyboard.
- Keyboard Guard: The rear edges of the tray are equipped with keyboard and mouse guards to keep devices safely on the tray, even if tilted at a negative angle.
- Cable Management: Cable clips are incorporated into the rear keyboard Guards
Note: Clips may not fit all diameters of keyboard or mouse cables.
