These ARMS are divided into two categories, Arms for vertical surfaces and Arms for horizontal surface applications. The vertically mounted 400 Series have up to 24" of vertical adjustability; you can easily adjust your monitor from standing to a sitting position or anywhere in between.

The 400 Series also allow you to easily position the height and angle of your monitor, laptop or keyboard for maximum comfort and productivity. The patented friction system provides smooth adjustment while maintaining touch screen stability without the need for knobs or levers.

Other features include: internal cable management that conceals and routes cables; internal steel construction that ensures long-lasting durability; sleek, durable, easy-to-clean plastic exterior; conformation to the Video Electronic Standards Association (VESA) Flat Panel Monitor Physical Mounting Interface (FPMPMI) Standard. These Arms are covered by a 2-year limited warranty on the internal gas spring and a 5-year limited warranty on other Arm components.
