Highlights:

Step 1: Put the Smaller Magnet in the Electrical Box

When installing drywall, place the smaller magnet in the electrical box before covering the box. Two stud locators on the back of the magnet fit over the screw locations in the electrical box. Use the arrows on the magnets to determine the direction to orient the magnets.

Continue installing drywall in the area.

Step 2: Use the Second Magnet to Locate the Box

When it's time to cut a hole in the drywall, hold the second magnet over the area where you think the electrical box is located. Make sure the arrow on the magnet is pointing in the same direction as the magnet placed inside the electric box. When you find the electrical box, the magnets will attract. Let go of the magnet. It will snap to the wall opposite the magnet inside the electrical box.

Step 3: Trace the Magnet

Make sure the outside magnet is straight, then trace an outline.

Remove the outside magnet.

Step 4: Cut the Hole

Safety Note: Make sure the electricity is off.

Use a drywall saw to cut out the hole. Take care not to cut into any studs nearby.
