Rectangular Electrical Box Cutout Tool - Accurate Magnetic Alignment

Description

Makes perfect drywall, wood paneling or plywood cutouts with no measurements. Magnets align with each other through up to 5/8” thick paneling, (depending on strength of magnets used), thus eliminating error-prone measurements. This design works with standard metal or plastic, rectangular shaped 2" x 3.5" electrical boxes. An optional handle is provided which can be mounted on the template tracer with a 1-1/4" screw and nylon lock nut.

How to construct:

The design makes use of strong 20mm dia. X 3mm thick Neodymium rare-earth magnets. Repeat the following step for both parts: 

With north polarity on the top socket and south polarity on the bottom socket, glue one magnet in each socket. You will need 4 magnets in total. Note: North polarity is usually indicated with a red dot on the magnet.

How to use: (refer to attached illustrations)

1. Install the smaller rectangular part into a standard electrical box using the screws that came with the box;
2. Temporary secure the drywall or paneling over the box.  Now take the larger rectangular part and move it around until it magnetically self-aligns with the electrical box underneath the paneling. Make sure the orientation is correct otherwise the circular unit will not attract & stay in place;
3. Draw the inner outline of the larger rectangular  part with a pencil or marker;
4. Lower the panel & cut the hole along the marked outline with a saw;
5. Replace the drywall over a perfect fitting cutout over the electrical box.
