This is a monitor arm for a single-screen display. It's a stand-alone type that can be installed simply by placing it on a desk. Recommended for those who want to switch to a stand that can easily adjust the monitor's up/down, left/right, and height. EEX-LA020BK All original parts are included. Original box is available. It weighs 6 kilograms, so it's heavy, but it's stable. The height can be adjusted to a considerably high position. ● This is a stand-alone type monitor arm. ● Compatible with VESA standards (75x75mm, 100x100mm) for mounting LCD displays. ● Supports the installation of LCD monitors up to 6kg. ● Convenient for replacing a height-adjustable base or for installing a monitor if you've lost the base. ● Allows you to adjust the height of the LCD monitor to match your eye level. ● The screen can be tilted up 60 degrees, down 20 degrees, and rotated 30 degrees left and right, and can be rotated 360 degrees. ● Non-slip pads are attached to the entire underside of the stand, which is recommended for preventing large monitors from tipping over. ※ The range of angle adjustment and rotation may be more limited than usual depending on the size of the monitor being installed. ※ The stiffness of the arm's movement varies depending on the weight of the monitor.
