Getting the Measurements Right: Blindmark Drywall Marker From "DIY Tools & Techniques" episode DIT-312

Figure A

One of the hardest parts of installing drywall is measuring and marking for electrical boxes. David reveals a tool that simplifies the task.

The Blindmark Drywall Marker is a set of two magnets (figure A) that work together to locate the position of electric boxes so you can cut holes for them.

1. When installing drywall, place the smaller magnet in the electrical box before covering the box (figure B). 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.

2. Continue installing drywall in the area.

3. When you're ready 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 you 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.

4. Make sure the outside magnet is straight, then trace an outline (figure C).

5. Remove the outside magnet.

   Safety Note: make sure the electricity is off.

6. Use a drywall saw to cut out the hole (figure D). Take care not to cut into any studs nearby.

7. Remove the magnet from inside the electrical box and you're done.
