This looks like a real bargain hidden amongst all the junk of the "catchathon".
Looks like model 60091.
"The Kensington 4-Position Monitor Arm with SmartFit™ System features independent height and tilt adjustments, It saves desk space by mounting onto your desk, and swivels the screen away when it’s not in use. With the Smart-Fit system, … The arm can support the weight and size of 15” to 17”, up to 10kgs [actually 20lb]."
This must be an old model from the "15-17inch 20 lb" description. Modern 22" wide displays are the same height as the old 17" ones, and only weigh around 4-5kg, so it should fit well. Please comment if I am wrong there. Portrait mode could be a problem.
Same VESA mount of course. It clamps to the back edge of your desk.
$19.95 + $9.95 post, discount for multiples. These usually cost more like $100.
what about my 27inch lcd? does it fit?
