Corner Sleeve DE400 Series

The DE400 Series Corner Sleeves 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 (23.25" wide) between the 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 large dimensions of the DE400 Series Corner Sleeve make it quite suitable for desk top keyboard and mouse positioning. The uniquely-shaped "wings" provide convenient mousing areas for both right and left-handed users. With a depth of 13.75" the DE400 Series Corner Sleeve will accept any common combination of keyboard and mousing device. 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 DE400 Series Corner Sleeve is available in two models — the DE400 can be easily adjusted to fit desks from 1" to 1.5" thick while thicker desks (1.5" - 2.5" thick) can be accommodated by employing the DE450 which is available by Special Order.

Note: While the DE400 Series Corner Sleeve provides a bridging width of 23.25" the overall width of 38.5" does require a fair amount of desk surface for installation. If there are space restrictions it may be necessary to consider a similar product with a smaller overall footprint.

• Accommodates Most Work Surfaces: The DE400 Model will mount to work surfaces 1" to 1.5" (2.5 - 3.8 cm) thick. The DE450 (available by Special Order) will fit desk thicknesses from 1.5" to 2.5" (3.8 - 6.35 cm).
• Low Profile: Humanscale Corner Sleeves are formed from heavy gauge sheet metal which provides rigidity while maintaining a very low profile over the mounting surface.
• Compatible with Most Articulating Keyboard Arms: The front lower lip of Humanscale Corner Sleeves are pre-drilled to accept most common articulating arms. The installation hardware includes bolts for securing these arms to the sleeve.
• Durable and Professional: Humanscale Corner Sleeves are formed from heavy gauge steel, finished with rounded corners, and powder-coated in Black.
• Easy Installation: Installation of a Humanscale Corner Sleeve is as simple as adjusting the thickness to match the thickness of the desk top (simple tools required) and then sliding it into position on the desk. However, it is generally recommended to secure it to the underside of the desk with the included screws or to use something such as double-sided tape to keep it from sliding.

• When considering a Corner Sleeve several factors should be considered.
  • First, determine if this is to provide surface area for deployment of a keyboard and/or a mouse. If this is the case you will want to ensure that the surface area is of sufficient size to provide a level surface for placement of the keyboard (at the minimum) or both the keyboard and mouse.
  • Second, if the Corner Sleeve is intended to be used for the mounting of a Keyboard Track and Tray you will want to ensure that the keyboard tray can extend far enough that you have practical access to both the keyboard and mouse without having to reach in under the desk top. With larger corner sleeves this is generally not an issue.
  • Third, you will want to determine whether the keyboard tray will need to be elevated level with the desk surface. This will require that the rear edge of the keyboard tray be positioned far enough out from the inside corner of the desk that the rear corners of the tray will clear the sides of the desk. This can usually be addressed by either utilizing a tray with the rear corners cut at a diagonal or by selecting a wider corner sleeve which will move the mounting point for the keyboard track further out from the inside corner. Doing this creates a wider space for the keyboard tray.
