CornerShaper Corner Desk Surface Extender


  • Turns a sharp-angled desk corner into a usable surface
  • Comes in five sizes and fits desks from 1" to 2.5" thick

  • Allows mounting an underdesk track for a keyboard tray

Corner desks are excellent for optimizing available worksurface area in smaller spaces. However, the sharp angle of the corner section often makes it difficult to utilize and results in wasted space. With the CornerShaper, you can turn almost any previously unusable desk corner section into a functional surface. The CornerShaper extends the work area, allowing not only more use of the desktop, but also provides the ability to mount a keyboard arm beneath it. An aesthetically pleasing, smart design and low profile makes the CornerShaper suited for most applications.

  • I just received my corner shaper. Where is the keyboard tray that comes with it?

    The CornerShaper does not include a keyboard tray. Those pictures are to show that a keyboard tray can be used with the CornerShaper.

  • Do I have to drill into my desk to attach this, or is it more of a clamp?

    You will need to mechanically attach it from the bottom of the surface.1/8" pilot holes need to be drilled on the underside of the desk so that is can be attached with the provided screws.

  • Does this come on and off easily, or is it semi-permanent?

    The CornerShaper is a semi-permanent fixture that would require the removal of screws to be taken off.
