At 27" wide, by 10.625" deep, the Big Keyboard Tray from Humanscale provides ample space for safely deploying a full-size keyboard and mouse on a single, level surface. When mounted to a height adjustable keyboard arm the Big Keyboard Tray becomes a versatile height- and angle-adjustable workstation accessory that can accommodate users of all heights.

The Big Keyboard Tray is composed of .25" thick rigid phenolic resin and is equipped with two foam rubber keyboard gripper strips to position the keyboard securely. Integrated 7" wide by 8.25" deep hard-surfaced mousing zones on the right and left sides of the tray enhance its versatility. Raised ridges with cable retention capabilties edge the sides and back of these surfaces to prevent the mouse from falling off. The front edge of the tray can accommodate either of the optional palm rest accessories.

Note: This tray can be mounted to the Ovation Low Profile Leverless Arm.

The Retractable Mousing Platform can be attached directly to the underside of a desktop surface or between a keyboard arm and tray. The mousing surface can easily be stored out of the way when not in use. The platform requires a mounting area of 19" x 10.25" and offers an 8.5" x 8.5" usable mousing/writing surface. When used with a keyboard tray (20" width maximum) and arm, the writing platform can be pulled out on the left or right hand side. An integrated safety stop ensures that the working surface cannot be accidentally overextended. The unit is composed of a black metal mounting bracket with a black vinyl-coated MDF board.

The DE100 Corner Sleeve from Humanscale can be used to create a usable workspace out of a tightly curved or inside right angled corner. The steel plate creates a diagonal bridge (20.375" wide) between the adjacent supporting surfaces, enabling the user to fully utilize the entire workstation. The user is now given access to an expanded work area (right, left and corner), enhancing the ergonomics of the workspace.

The shape and dimensions of the DE100 Corner Sleeve make it suitable for desk top keyboard and mouse use. With an upper surface width of 29.5" and a depth of over 12.25" the DE100 Corner Sleeve is compatible with most common keyboard and mouse combinations. It is also equally suited to keyboard arm and tray deployment as the underside of the unit is pre-drilled to accommodate most common keyboard arms with no additional modifications required. The Keyboard Tray Corner Sleeve can be easily adjusted to fit desks from 1" to 1.5" thick.

Note: If the bridging width of the DE100 Corner Sleeve is too great a smaller alternative solution should be considered.

The Kinesis Solution Phenolic Tray from Kinesis is a strong, non-flexing tray with an ultra-thin profile. The bowed back edge has a lip about 1/4" high to prevent your keyboard and mouse from falling off whenever the tray is adjusted to a negative incline. The trays come in two models of width - 26" and 30".

NOTE: This tray will ideally work with the Ovation Low Profile Leverless Arm.

The 3M Gel Wrist Rest Platform for Keyboard is designed for users who want to reduce wrist extension (i.e. an upward bend at the hand) with its associated risk of injury to the wrist and forearms, when working with a conventional keyboard at a seated or standing workstation. The platform is placed directly on the desk surface to provide a base for the keyboard. The gel wrist rest is secured to the platform in front of the keyboard, providing support beneath the heel of the hands to keep the forearms, wrists and hands in comfortable alignment when typing.

Two sets of optional rubber feet are included, and can be attached to the underside of the platform to create either 5° or 10° of negative tilt for the keyboard to provide further insurance against wrist extension.

At 19.5" wide, the platform and wrist rest accommodate standard keyboards with built-in numeric keypads. The wrist rest is 0.25" thick and made of gel-filled leatherette embedded with antimicrobial properties to inhibit the growth of bacteria.

With a total width of just 19" but a depth of over 12.5", the Diagonal Keyboard Tray from Humanscale is designed to fit in angled corners that are tighter than average. The 15.5" long rear edge angles outward at 45º to get to the full 19" width. The rigid phenolic tray features foam rubber keyboard gripper strips to ensure the keyboard is securely positioned. The tray is also capable of accepting the optional palm support. This keyboard tray can be equipped with an optional swing-out mousing surface to accomodate a traditional mouse but is also deep enough for a central pointing device such as a RollerMouse or Mousetrapper.

Note: This tray is compatible with the Ovation Low Profile Leverless Arm.

The Keyboard Drawer Underdesk SuperShelf from Kensington is a cost-effective solution where a desk surface is up to 2.5" too high for the user. Because it is a "tray" design the keyboard and mouse cannot slide or drop off of the tray but this also tightly restricts the space for keyboard and mouse. This tray provides a limited 24" width space to place a keyboard and mouse which means that it is better suited to use with a compact keyboard that has a reduced width. Cord routing guides permit cables to drop through the rear of the tray. The SuperShelf is also equipped with a removable foam palm support.

The Keyboard Drawer is equipped with a glide mechanism that permits easy storage below the desk. The mounting brackets offer four mounting heights (half-inch increments)so users can position the drawer at the height best suited to their needs. This drawer does require a minimum width of 29.5" width and 18" of depth on the underside of the desk. With the palm rest installed it can accommodate keyboards up to 9.5" in depth, 11" in depth without the palm rest. When fully deployed the tray extends about 10.5" from the front of the desk.

At 27" in width and 11" deep the HDPE Keyboard Tray from KV Waterloo provides sufficient space for virtually any combination of keyboard and mouse. The rigid 0.5" thick tray is formed from HDPE (High Density Polyethylene) which is fully recyclable and features non-slip strips for secure keyboard placement as there is no rear lip on this tray. Included with the HDPE Keyboard Tray is a removable gel-feel foam palm rest. The HDPE Keyboard Tray features a universal mounting pattern for easy attachment to any KV Waterloo keyboard arm.
Note: One of the pins which holds the palm rest in place no longer inserts into the rest. This could easily be addressed by some double-sided tape being applied to the underside of the rest.

The MDF Keyboard Support Tray from KV Waterloo provides users with a rigid surface for both keyboard and mouse.
