I used this to add an outer exit from an inner loop. It is very well designed and perfect for my needs. I particularly like that the IN BOX is a unit that combines the electrical box and the weatherproof cover. The kit includes IN BOX, mounting adapter, screws for adapter and box and self-adhesive sealant. You can use the adapter as a template to cut an opening in fairings and panels. After that, you need to fix the adapter and IN BOX on the outside wall, lay the wiring and install the socket.
