ZepSon Laptop Arm Mount Tray, Steel Notebook Holder, VESA 75*75mm Monitor Arm Mounting Hole Compatible, Anti-Slip Design, Suitable for up to 17 inches I purchased this last year but am selling it now as I no longer use it. The condition is good. The following is a reprint from Amazon: This laptop arm mounting tray fits VESA 75x75 mm holes and can accommodate laptops up to 17 inches. Most VESA mounting arms on the market are compatible. It provides an ergonomic workstation for your laptop and helps to make a monitor arm a laptop VESA mount. You can raise the height of your laptop screen for easy viewing and adjust it to reduce neck strain. Silicone rubber is placed in six places on the mounting tray to prevent scratches and slippage on the device. The vents greatly improve breathability and keep the laptop cool. Metal accessories are included for easy connection of the tray to the VESA bracket. It uses 2mm thick steel. The material is excellent, the polished surface is painted black, the texture is high, and the size is 31x23.5cm, which is the same as most laptops! With a load capacity of 5KG and a sturdy steel frame structure, the monitor is always safe and reliable. *24-month warranty from the date of purchase.
