This is another simple wall mount that can be utilized for various types of hardware. From monitors to larger tablets and even macbooks. Originally designed to function as a support for my AOC USB3 monitor that liked to have easy access to in order to test devices on. The opening is about 19.5mm wide and there are two holes (approx 4.7mm wide) for mounting screws if required. Though as with other mounts depending on the size of the object, adhesive may suffice.
