Abstract: An apparatus for marking the location of fixture and electrical boxes during construction or remodeling of a structure, having a pole with an attached ceiling marking assembly concentrically situated above a marking hole. A spring tensioned bolt is aligned with a ceiling fixture, or a wall marker attached to the side of the pole is aligned to a wall fixture and a mark is made at the base of the apparatus. A level ensures that the pole is properly oriented in a vertical direction. After hanging a rigid covering, such as drywall, the apparatus is aligned in position on top of the previously made floor marking, whereupon the bolt is released via a catch to make a mark on the ceiling drywall where the fixture box is located. Alternatively, the wall markers are used to mark the drywall locations of fixtures located on walls of the structure.
