Easily mount this laptop tray to a VESA monitor mount, stand, or arm, and free up space on your desk while still having full access to your laptop. The tray (11.8in x 11in/300mm x 280mm) is large enough to hold a laptop between 9.4 - 16.5 inches wide, 1 inch tall, and weight of up to 10 lbs (4.5 kg). The monitor mounting arm or stand is not included, and it must support 75x75mm and 100x100mm mounting patterns, and the weight of the laptop plus tray.
