This is a wall phone mount using the Hex Connect mounting system.
Included are both standard and XL size Hex Connect mounts. Both have dovetail and through-hole mounting options.
Install Instructions:
Dovetail: Screw the small dovetail mount to a stud or other solid part of the wall. Slid the dovetail Hex Connector onto the dovetail mount.
Through-hole: Screw the Hex Connector straight to a stud or other solid part of the wall.
Standard vs XL pros and cons:
Connector
Pros
Cons
Standard
Thin enough for proper Magsafe support (2mm)
Slimmer case is more convenient for everyday use

Probably stronger than you would expect :)
Not as strong as XL

Thicker case is less convenient for everyday use

Using Hex Connect:
To connect: Align the hole in the phone case to the Hex Connector. Make sure the back of the phone is flat to the face of the Hex Connector. Either push the phone straight onto the connector or start a little clockwise and turn the phone counterclockwise as you push for a smoother connection action.
To disconnect: Pull slightly on the phone, then turn counterclockwise while holding slight pulling pressure on the phone.
Tip for Left-Handers: Mirror the connector in the slicer to reverse the rotation direction. The case design is ambidextrous.
If you already use the XL case for other accessories use the XL. If not, I would go with the standard size.
