Abstract: A method and system of marking location for installation of a wall-box. At least some of the illustrative embodiments are systems comprising a base member that sits upon the floor (the floor defining a horizontal plane), a vertical member coupled to the base member extending substantially perpendicularly from the horizontal plane, a moveable member slidingly coupled to the vertical member (the moveable member selectably positionable along the vertical member), and a marking member coupled to the moveable member. The marking member marks a surface substantially at an elevation of the moveable member.
