The Blind Mark will help you get perfect drywall cutouts with no measuring. Just insert the target in the receptacle before hanging drywall. When you’re ready to cut the hole, hold the Blind Mark Locator magnet over the area where you think the receptacle is located. When it finds the receptacle, the magnets will snap precisely into place where the receptacle is located. Traces around the locator, cut, then install. With the Blind Mark you simply put it up once, cut the hole and you’re done.

  • Works on drywall, plywood, particle board, laminated flooring, Masonite, exterior siding, cement board, tile backsplashes, slate and more
  • Target magnets fit standard single or multi-gang, standard or thin plastic or metal boxes for any new construction installation
  • No more measuring and no risk of mis-measuring – just locate the receptacle, mark, cut and you’re done
  • Twice as easy as other receptacle locating methods because you only lift the drywall once
  • You can even use it as a stud finder
  • Includes 3 target magnets so you can easily find multiple boxes at once, saving time

Rated 4.7 out of 5 by 43 reviewers.
Rated 5.0 out of 5.0 by Works exactly as advertised, easy to learn to use I bought this to locate electrical boxes behind 5/8" drywall, and it works extremely well. A couple of things: 1. If you're using the typical plastic nail-on new work boxes, remove the little plastic spacers from the side of the box against the stud with a pair of pliers or a razor knife. Otherwise, you have to cut out quite a bit wider or risk blowing out the drywall on the stud-side of the box. 2. I found using a pencil rather than a sharpie made it easy to follow the line accurately. 3. I used an oscillating multi-tool with a Dremel drywall jab-saw blade. This worked very well. It's loud, and cuts a lot slower than a rotozip, but it won't get away from you. I found it best to try to cut the hole tight, pry the piece out and see where the box sits. I had to enlarge a couple of holes slightly before the drywall would fit around the box. Better too small than too big, you can always cut out more. Just don't push on the sheet until you pry the piece out and see how accurate your cut was. 4. Obviously, if you hang sheetrock for a living, you probably can find the boxes and cut them out with a rotozip in your sleep, without using this tool. However, this tool is great for someone starting out or who occasionally hangs drywall. After cutting a few holes, probably too large, you'll get a good feeling as to where to cut in relation to your pencil line. After the first few boxes, I was cutting extremely tight holes without even trying. I've attached a photo of the last one I cut it, nice and close. December 22, 2013
Rated 5.0 out of 5.0 by Awesome I love this product for marking boxes and getting perfect cutouts. Because of this product, I also picked up some super strong little magnets that make it easy to mark the corners of electric panels and windows and doors. August 22, 2015
Rated 5.0 out of 5.0 by Best tool to locate electrical boxes ever I am building a new wood shop and wanted a lot of electrical outlets, I have never been good at locating the boxes and was dreading the thought of all the boxes I wanted. I am putting up 7/16 OSB. I have used the Blind Mark XT and cannot believe how easy it is. I even find myself enjoying cutting out the holes and watching them fit perfectly every time. The only thing to watch out for is to make sure the both the interior and exterior locator is pointing the same direction or you will be 1/2 a hole off. This product amazes my friends. Can't recommend this too much. July 13, 2015

Rated 5.0 out of 5.0 by Works great I have tried in the past to use a Roto Zip to jab in and cut out boxes, and have had issues when using plastic nail-on boxes. The problem with following along the outside edge of a plastic box, is the tendancy to cut into the box. I'm sure professionals have mastered this, but for home owners or do-it-yourselfers, this is an issue. Measuring and cutting the boxes before hanging is slow and easy to mess up on, and a lot of work, especially on ceilings. The Blind Mark makes this so much easier and faster. I still use the Roto Zip, but having the line ensures you don't cut into the box. Tracing along the line is also helping me get better at feeling the box edge with the Roto Zip. October 23, 2015
Rated 5.0 out of 5.0 by works great love this product for marking boxes and getting perfect cutouts. Because of this product, I also picked up some super strong little magnets that make it easy to mark the corners of electric panels and windows and doors. Example: the drill was really easy to assemble, lightweight and not noisy. I am really pleased with the battery life and was able to use the drill without charging for over an hour of heavy duty use... November 8, 2015
