A basic two piece mount to attach a tablet to the wall.  The wall plate rail can be screwed into a standard US electrical box or directly into a stud or anchors with 6/32" counter sunk screws.  The clamp plate has plenty of surface area to use command strips to attach to a tablet or other flat object.  The clamp plate slides down from the top onto the wall plate rail for easy access.  A slot for charging wires is available. 

I am using this mount for a tablet running Home Assistant in the Fully Kiosk Browser attached to the low voltage electrical box of a previous security system.  Here are the items I used:

• Lenovo Tab M10 Plus Gen 3
• 6/32 1 ¼" counter sunk screws (Qty 2)
• Small Command Strips (Qty 4)
• USB C Short Flat Cable: A longer one would be better
• USB C Terminal, Type C Female Screw Terminal Block Connector
• AC100V-240V to DC 5V 2A Adapter Supply
