The 7550 Sit/Stand mechanism may be used with any of Arbutus' Keyboard trays. This is a lift and lock style mechanism, thereby replacing knobs or levers with a one step single hand operation. 360 degree swivel operation with a vertical adjustment of 10.5" for true sit/stand operations. 

Arbutus designs and manufactures wrist rests specifically for our line of keyboard trays. The foam pads are covered in a soft, leatherite material which wipes clean and are attached to the surface of the tray with pop-out buttons.
