Computer monitor arm (CT11)

Used with a 27in screen weighing 4.5kg although wouldn't use it with anything weighing more than that.

I don't have the screws to attach it to the monitor. It's the arm only.

 Ergonomic Height Adjustable Monitor Bracket Stand for 17”- 32” VESA Dimensions 75x75-100x100 mm, Weight Capacity up to 8 kg
