Abstract:
1. A construction location system, comprising: a mounting disk including a mounting magnet, the mounting disk including a mounting perimeter configured for insertion into an electrical box whereby the mounting perimeter engages a perimeter wall of the electrical box such that said perimeter wall is displaced and the mounting disk is coupled to the electrical box; and a seeker disk including a locator magnet having a central aperture, wherein the seeker disk is adapted to be positioned on a surface covering the electrical box such that magnetic interaction between the locator magnet and the mounting magnet results in the locator magnet and the mounting magnet being aligned on opposed sides of the surface and wherein cutting a hole through the surface as guided by the central aperture causes a hole saw to remove the seeker disk, a cut portion of the surface and the mounting disk, and wherein the mounting perimeter comprises a non-round perimeter, and the non-round perimeter includes a first diameter and a second diameter, wherein the first diameter is less than an opening diameter on the electrical box and the second diameter is larger than the opening diameter.
