About This Product

The Plug Mark is specifically designed for locating existing outlets in rehab and remodel projects. The Plug Mark will help you accurately locate and cut electrical outlet access holes in drywall, sheet rock, paneling and many other materials with no measuring required.

Cut out, remove the target magnet and you're done.

    How do I use this in the garage where I have 4" metal boxes? Some with double outlets, some with single.

    Answer This Question

    If the outlets are already installed in the boxes, they the PlugMark target markers can be installed in the plug and the locator can be traced once it has located the target(s). If the outlets are not installed in the boxes, the Multimark tool may be the way to go as the target can be mounted on an angle and then the locator can be traced on the four corners for the 4” box outline. A quick video of some of the uses of the BlindMark is shown below: https://youtu.be/ou89xuB9yUQ

      What tool are you using to make the cut. It must be a very shallow cut considering the wiring is in place.

      Answer This Question

      We don’t specify what tools to use, but tools that have been used are RotoSaws, Rotozip, drywall saws and razor blades. The advantage of using the rotary saws and razor blades is that the height can be adjusted.

        Should you turn the power off before using magnets ? Everything I've read so far, indicates magnets can mess up wiring . Thoughts, suggestions or knowledge?

        Answer This Question

        We have not performed any testing in this area, but no electrical current is being conducted through the plastic, so it shouldn’t be an issue. From a safety standpoint, the power should probably be turned off anyhow if you are cutting around an electrical outlet.

          Does this work on tin / metal !
          ByMay 8, 2023
          1 Answer | 
          Answer This Question

          If the metal does not attract magnets, like tin, then it should work, depending on the thickness and distance from the outlet target magnets.

            Does any part stay in outlet can the parts be used for multi outlets

            Nothing stay as in permanently and no, this is designed for a single outlet.

            By|May 5, 2023

            Yes, since you have two targets, you put one target into each outlet, set your drywall, locate the first target, trace around it and then find your second target, trace around it then RotoZip around your trace lines.

            One outlet at a time, but it can be used many times over

            You can do two outlets at a time, remove the targets and move to the next two outlets after cutting them out.

              How does this product work with plywood?

              Answer This Question

              Yes and no. depends on thickness.

              By|May 5, 2023

              You place the Plug Mark in the socket and then after putting up the plywood your use the locator, mark the hole and cut it out.

              By|May 4, 2023

                Yes, any non-metal walling material... that strong magnets can 'see' each other through.

                It works well on 7/16" plywood, acceptable on 1/2" plywood, you just have to slide it around a little bit to make sure your lined up square and poorly on 3/4" plywood. Plywood is a denser material than drywall so the performance is a little less.

                I have not used this tool for plywood, it's made more for drywall because it uses magnets, but you could test it out if you want, Good Luck !!

                Careful with GFCI's!
                This is a great concept and could greatly improve cutout accuracy in remodel situations; however, the target pieces fit very tightly in to my GFCI breaker(s), and cracked the plastic surrounding the ground-terminal holes.

                  They actually work pretty good! Just plug the Target Plug Mark into the outlet and then use the Locator to trace out and cut the drywall, works pretty good! It comes with two Targets and one Locator. There are magnets that hold the locator in place on the drywall (I used 1/2" drywall). I tested them on two 1/2" drywall boards sandwiched together and the locator still stuck which means the magnets are strong. I've also tried 7/16" board and it works as well.

                  Plug Mark Magnetic Drywall Cutout Tool for Existing Outlets Model 8120 by Calculated Industries Packaging: Hanging blister pack Contents: 2 targets plus 1 locator First Impressions: Simple and intuitive tool Description: The thin targets plug into the existing electrical outlets where a sheet of sheetrock or paneling will be hung. Then the panel is installed. Next the locator centers itself over the target and shows where to cut out for a perfect fit. Usage: The target plugs right into the ground ports of the duplex outlet. Because it is very thin, one can simply hang a panel of sheetrock or plywood right over it. The tip here is to fasten the panel down, but not too tightly near the outlet. Next one will place the locator over the area and watch the two magnets on each automatically align with each other. Use a light touch as you slide around the area, and feel how they find each other without a lot of trouble. Then simply mark around the locator with a pencil or pen, while holding the locator plumb by eye. Remove the locator and cut out inside the lines. I had a helper use a Rotozip tool, because we could set the estimated depth and do a plunge cut. Very easy. After that, remove the cut out material, and retrieve the target. There is one little thing; one must now remove the screws from the outlet and work the outlet tabs out from under the panel that was installed, so as to make the outlet and its cover align at the new shallower depth. Then reinstall the screws, and finish fastening down the panel. This kit would be more complete and useful if it included similar tools for existing switches, but oh well. Overall Thoughts: I find this to be pretty slick when going over existing outlets. It is fast and convenient. Every outlet comes out perfectly, and this is worth the price.

                  This outlet locator works pretty well. However, it does have its limitations….the inserted piece needs tape added to the plastic ‘ground’ pin or it falls out of the outlet. Also, move the larger magnet (outer) piece up as much as possible or your drywall cutout will be off. It doesn’t work on thick material larger than 1-1/2”. The arrows should point up.

                  I used it to locate electrical boxes behind 1/2 inch dry wall. It did not work at all with GFI receptacles. While the magnets did work to generally locate a box, the accuracy was not acceptable to me. I went back to measuring. I did not use customer service.

                  Just as advertised, this works! Perfect location marking for outlets. needed to expand the cutout opening slightly for a perfect fit. Probably should cut on the outside of the traced line.
