This is a heavy duty SpaceTek LCD-CS Clamp Stand for a single monitor. Condition is excellent, entirely in working order and includes a wrench for mounting/adjustment. I used it in my workshop where I had a computer but didn’t want to have the monitor on my workbench. This thing is built like a tank, you won’t possibly be disappointed by the quality. And it’s easy to grab the monitor and move it around for better viewing WITHOUT worrying if it will stay where you want it; this thing never drops or slips at all. I wanna say they sold for about $130 when new? Here are some details from the manufacturer... Meets VESA mounting standard 75mm or 100mm (Most LCD's on the market have this bolt pattern) Full articulating, gas assist/friction system, 360 degrees swivel on the base and top plate rotation. Gas Spring system adjusts the angle to most comfortable working position. Holds a weight of 25lbs. If needed, the stand can also be locked. Dynamic arm easily adjusts to suit your needs, up and down, front and back, left and right. Cable manager organizes cable in place Can be clamped to a table top or mounted to a wall
