Knoll Under Desk Mount Adjustable Keyboard Tray

Description

This is a very high quality product with some really nice features.
Look closely at the photos of this listing to see what it can do.
The platform is large enough to accommodate my old clunky MS keyboard and still have room for my big old mouse so it will probably be large enough to work well with almost anything out there. 26 Inches wide and 11 inches deep including 2-1/2 Inch wrist pad all across the width.
The platform tucks neatly beneath the work surface when not in use. It can be pulled out and lifted infinitely to any height you wish from just below the work surface up to 5 inches above the work surface. When pulled out it can be swiveled either to the right or to the left to accommodate just about any position you might desire in relation to your monitor.
The platform can be adjusted to tilt towards you or an inverted tilt away from you.
I have installed this at my work space which is only 20 inches deep, so I needed to remove a few inches of the track before it was installed. The only negative result was that it won't store completely under my work space which is no problem for me. (24 inch work station depth would be ideal)
I researched the value of this item by going to the Knoll Extra website and finding it or something almost exactly like it on page 164 & 165 of their catalog with the list price of 0 and more. I also found the same brand and featured item on another online retail site at over 0. I found another eBay seller with one for over 0 which has a bent or broken part.
I purchased many of these, brand new, still in their original cartons as surplus from the State of California.
Mine was easy to install with all the hardware included in the box. Once installed, I realized how much I had been missing by not having one. All I had before was a  pull out plastic tray. Boy what a great improvement over that.
The carton is 7 X 24 X 27 inches and weighs about 21 pounds
