After I sold my laptop and me a "All-in-One" - had bought PC, I wanted to make my keyboard and mouse a little deeper and bought this one keyboard tray.
Goods arrived quickly and well Verpack incl. Assembly instructions and all necessary screws with me.
Both the metal rails and the keyboard tray are very well made and give no reason for complaint.
The keyboard tray is 800 x 400 mm in size and has a rounded front edge.
The clearance between desktop and keyboard tray is actually about 71 mm.
Since my desktop has under the worktop a "stability strut" and the keyboard tray thus approximately 1 cm had stood out in my case, in the inserted state, I have resorted to me with a disused walnut-colored shelf.
That shelf I have Mr. cut two strips, which I speak used as spacers between desktop and the angles of the keyboard tray.
Thus, the above-mentioned internal dimension despite an improvement in my case to approximately 87 mm, the whole thing but does not detract.
Installation of the keyboard tray was quick and easy. All necessary screws are included. The installation instructions contained had I not needed.
All in all, can issue a buy recommendation and awarded full 5 stars I for this keyboard tray.
Greeting Markus
