Desktop mount for TFT LCD monitors.
Setup for this can be a bit odd, as you must mount the monitor into the arm before clamping down the arm. My other arm I've bought here was a simple horizontal swin mount, which I've mounted to the side of a shelving unit on my desk, and came wih 2 thumb screws to tie down the slide-in monitor back plane.
Overall, it wasn't my ideal setup, but hindsight never ceases. It's serving the purpose, and seems to be very tough and resilient. If you're having issues with the swivel, you'll have to adjust those screws to find the "sweet spot" for your liking.
I have dealt with MCM Electronics a number of times and have been more than satisfied.
