Thank you for your interest in the product. I'm selling this monitor mounting bracket because I replaced it. It works without any problems. There are no missing accessories. Everything in the photos is what will be sent (no outer box). It has a weight capacity of 12kg, an arm length of 13cm (from the wall mounting bracket to the display mounting bracket), and can be adjusted in two directions: left/right and up/down. When shipping, the arm will be folded, so please adjust it with a wrench when installing. Thank you very much.
