Frequently Bought Together

Product Overview

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

Answer: 
Yes, it will. But you may have to cut inside the lines drawn around the template. (The device that goes on the outside of the wall.) This is because the template is sized for single gang PVC boxes, and the galvanized box will probably slightly smaller. It depends on who made the box, and the style of the box. This is especially true of boxes that have the holes for device mounting outside the box.

Answer: 
It depends if there are holes at the top and bottom (the ones for outlet attachment). If these are anywhere in the range of 3 1/4 to 4 inches in height, then this kit will work, as it has adjustable springs as well. You may be able to put two or three of the magnets side by side to get your desired box cut as well.

yes it will because it just fits into the existing screw holes and it holds the magnet piece in place until you match it up with the locator side

This is Jennifer of Calculated Industries Marketing Dept. and yes, the targets which go into the outlets, can be used in any type/material box - plastic or metal. If you have a multi box - use a target in each end. Hope that helps!

It depends on how big the cutouts for the devices are, and if the ears were removed from the devices. Remove the wall plate, and look to see if the paneling will clear the device when you remove it.

Yes, unfortunately, you will have to remove the outlets because the space is needed for the magnet. That's really the only con I find with this kit.

Answer: 
You will need to remove the switches and outlets hardware so the base magnets will be flush with the edges of the electrical box. This allows you to screw the drywall down before you do the cutouts and the finished cutouts will be flat and perfect.

Answer: 
The tool requires that the "target" be placed in the box, so that the "locator" can find it. It will be necessary to remove the outlet or switch (but probably not the wiring) to provide room for the "target" in the box.

Answer: 
Yes. You will need to remove the outlets and switches - mark the wires (load/line if necessary) and put wire nuts on each end and push the wires deep back inside the box before placing the Blind-Mark box locator over the electrical box. Always remember to cut the power before working with electricity. Install drywall and simply locate the box with magnet and cut. That easy.

Answer: 
If you mean will you have to unscrew the outlets and switches from their electrical boxes, the answer is Yes (be sure to turn off the power first before fooling with them!).
The reason is that the metal tabs ("ears") at the top and bottom of each outlet or switch are screwed down tight against the paneling (you will see that once your remove the outlet or switch covers). Your paneling may be thin enough Read More
If you mean will you have to unscrew the outlets and switches from their electrical boxes, the answer is Yes (be sure to turn off the power first before fooling with them!).
The reason is that the metal tabs ("ears") at the top and bottom of each outlet or switch are screwed down tight against the paneling (you will see that once your remove the outlet or switch covers). Your paneling may be thin enough or made out of cheap enough material that you could "possibly" tear it off around the outlets and switches without bending their metal tabs, but think about this - how are you going to put the new drywall in place over these installed outlets and switches?
You can't cut the new holes in the drywall large enough to go over those metal tabs of outlets and switches already in place because for a correctly finished installation the metal tabs should be screwed down flush onto the new drywall - if the cut-out holes are too large, there won't be any drywall for the tabs to be pressed against.
I'm in the process of replacing some water-damaged drywall myself. Pulling off the old damaged drywall with the outlets in place was easy - the drywall just broke off around the metal tabs. I was hoping to figure out a way to leave the outlets in place and thus save time when installing the new drywall but ran into the same problem as you. I even thought about bending the metal tabs forward to be parallel to the floor so a tightly cut drywall hole could be slid over them and then the tabs bent back into place against the drywall but I didn't go that route for a couple of reasons - the metal tabs might break off with too much bending back and forth, but more importantly I was going to need the outlets removed from the electrical boxes because I was going to roto-zip the holes with the drywall loosely hung in place and needed room in the box for the roto-zip bit to plunge into to start the cut.
So, unless a Pro or someone else has a great time-saving tip, the answer is going to be Yes, you will have to remove the outlets and switches first before tearing off the plywood. (Remember to cut off the power to those outlets and switches first and to leave it off in that interim loose wire state!)
(BTW, you may have a secondary problem you're going to have to address - assuming your current plywood is thinner than the drywall you are putting in, that means the electrical boxes will not be flush with the new drywall. Search "outlet box extensions" here on homedepot.com and choose from among various options - pricey box extenders, relatively cheap spacers to put on the screws to make the outlets and switches stick out further, etc. You could also pull the electrical boxes off the studs and then re-nail them after repositioning them to be flush with the new, thicker drywall but that's a lot of work and you might crush/bend/crack the electrical box pulling the nails, depending on how old the original installation was and whether the boxes are metal or plastic. Good luck.) Read Less

Answer: 
Yes, it should work, but keep in mind the maximum thickness these magnets will hold is 3/4 inch, no more. If you're keeping the drywall on, you'll need to temporarily remove the outlets to make space for the magnet that goes underneath.

Rated 4.7 out of 5 by 61 reviewers.
Rated 4.0 out of 5.0 by Very Cool Device! This is an ingenious little device. As many other reviewers have stated, cutting drywall for electric boxes is a time-consuming pain for the average DIY. I am no different than most, and have tried almost everything (lipstick, nails protruding from the box, measuring tape, etc.). And while I love using a Roto-Zip tool for this type of job, who hasn’t made a mess of a plastic box? This product works very nicely, and it’s close to perfect. The tool set consists of 3 “targets” (square magnetized blocks that fit into a standard electrical outlet/switch box) and 1 “locator” (a square magnetized block that will line up with the target that is hidden behind the drywall. Each of these blocks has two magnets with different “poles” meaning that each magnet will only gravitate toward the magnets on the other side of the drywall, that is the opposite pole. This means that the blocks will line up “almost” perfectly with each other, essentially making it impossible to goof by placing the locator upside down. In fact, I tried to place the “locator” upside down and it was repelled by the target magnet (simple concept, ingenious application). When I say the product is “almost” perfect, it is because, if the target and the locator are not both plumb, it is possible that the “locator” will not line up exactly with the real location of the target (see picture), it may be off-plumb by several degrees. Before using the device for the very first time, it may be worthwhile to set the target and the locator near the edge of your sheet rock and place the target slightly off plumb to see how it works. One last comment – these magnets are SUPER strong. If you are holding them with your fingers, take care not to bring the locator and the target close together, as they can snap together quickly and pinch your skin. June 20, 2016
Rated 5.0 out of 5.0 by Fantastic Product For years and years I've been doing construction and renovation jobs for my business, family and friends. Doing proper cutouts in wallboard for switches, outlets and light fixtures is a time consuming exercise in the ability to take accurate measurements. It's all too easy to get distracted and ruin a sheet. I spotted this very ingenious tool on HD's site. The one major drawback for me was that the outlet or switch has to be removed from the box to use it. It's perfect for new construction, before the outlets and switches are installed but the time it takes to empty and refill the boxes kind of negates the time saving factor for renovations. With no projects currently in the works I decided to test its accuracy by nailing a new box to a 2x4, inserting one of the three targets included and screwing a scrap of wallboard on top. The locator snapped to the board instantly but something didn't seem right. Sure enough, when I looked behind the board the top magnet of the locator was attached to the bottom magnet of the target. I discovered there are two simple solutions to identify this when it happens in the field. One is to take a measurement from the center of the box to the floor before starting the install or, a quicker way, is to twist the locator. If it's set on both magnets it will resist the twist. If it's attached to only one magnet it will twist easily. I corrected the problem, outlined the locator and went to work with my Roto-Zip. Staying just outside the line I cut three sides quickly but the fourth side, next to the stud, caused a problem. The bit wouldn't go in deep enough to cut the wallboard. In their video their box is not touching the stud so the bit has clearance all the way around. For me, not a deal breaker, I used my multi-tool for the final cut. The cutout was perfect. No need for Midway or Jumbo plates. This will be my "Go To" tool for new construction. While perusing Blind Marks web site I noticed they have a box locator set for renovations which doesn't require outlets to be removed. Won't work for switches. It's their model 8120. Images 2 and 3 below show this product. Blind Mark includes a one year limited warranty on this product. June 18, 2016
Rated 5.0 out of 5.0 by Great product that saves time This is a great product that allows you to have perfect electrical cutouts in drywall, paneling, or thin plywood. The final product is a perfect cut every time with no measuring. Place the base magnet in the outlet then cover the outlet with the finish wall covering drywall or paneling, then attach the top magnet on top of the drywall and it will stick to the base magnet, trace around the top magnet, then cutout and you have a finished electoral box the is completely perfect. It works with any size electrical box to produce perfect cutouts every time with zero measuring. Love this product. Great time saver. June 25, 2016
Rated 5.0 out of 5.0 by Good Time Saver This is a great tool to have around the house if you have drywall projects. The tool is very easy to use and very accurate. I am not a drywall guy by any stretch of the imagination and usually I end up butchering the sheetrock when I am finished. Not with this tool. Now using this tool everyone can have professional looking cuts around switch and outlet boxes; Keep in mind though that this is for new construction with no wires in the box for room for the magnet to sit in the box. A good tool for cutting holes in sheetrock for the guy that's not a carpenter. I recommend this tool. July 8, 2016
Rated 5.0 out of 5.0 by OMG--- This is the Greatest TOOL! This is the neatest tool I have run across in quite a while-- It is very simple to use,good clear instructions and makes life SO much easier when trying to cut the electrical outlets in so many different applications of products. I have used all kinds of gadgets to mark the box (lipstick,nails,tacks,etc) in the many years I have done jobs and NOTHING is as great as this tool! When I showed this to a friend of mine who has been a carpenter for years, he was so impressed he ordered one from HD right away and uses it all the time in his jobs now. Any professional OR DIYer needs this kit for sure!! June 28, 2016
Rated 5.0 out of 5.0 by Big time saver, wish I had these years ago These are SUPER cool, ones of those tools you wish you had years ago. Material / build quality is great. The plastic is good strong plastic not the brittle stuff. The magnets are unbelievably strong. No exaggeration, I was playing around and just stuck the magnets together without any drywall separating them and it took almost all my strength to break them apart again. If anything the case is the cheapest part of this package. Usage is very simple. The outlet side uses a spring clip to hold itself in place inside the box, and sits flush with the edge of the box. Slap the drywall up there, pin it with a few screws to get your hands free then just probe with the other half. When you get near an outlet you will KNOW... those magnets practically rip it out of your hands and stick it to the drywall. The small magnet targets plus their strength had about a 90% success rate of being perfectly plumb/straight. I checked it every time and only a few times did it need a slight nudge to make a square outline. Trace around the box then cut on the line. Really can't make it much easier. The only tip I have is make sure you check the trace tool against your box first - you'll wan't to know if you should be cutting on the outside or the inside of the line you trace. June 29, 2016
Rated 5.0 out of 5.0 by Ingenious! Not just for drywall!! What an ingenious idea. And nice packaging. I really love gadgets that come in their own box, clearly labeled and with instructions. First of all these are STRONG magnets. Don't get them too close to anything that could be damaged by a magnetic wipe, like credit cards, etc. Don't limit your thinking to drywall. I try to stay away from those applications, but I do tile and often install backer boards on walls that have multiple outlets, so I did a test on many different products to see how well this worked. Performed perfectly on these surfaces: T-111 exterior siding, cause you know you probably have exterior outlets 3/4" plywood, interior and exterior Interior wood paneling 1/4" tile I have a table with 12x12 tiles set in special steel plates and the magnets locked (1/2" combined) Tile backer boards of all kinds After about 3/4" thicknesses, the magnets don't have much pull but I can't think of an application where that would be an issue. June 26, 2016
Rated 5.0 out of 5.0 by Talk about breakthrough technology. . . Wow, this is cool! I do a lot of inside work and let me tell you, the BIGGEST waste of time for me is finding outlet boxes. It's so frustrating when you can't see where you're cutting and end up making a hole that's too big and having to do unnecessary patching. Well, this tool takes all the guess work out of it. Unlike press-to-mark methods where you have to align the paneling then take it off again, this kit is more straightforward. All you do is place the target magnet into an open outlet box and pop on your drywall like usual, avoiding the area/3 studs around he outlet. Then, all you have to do is drag the magnet over the area until in snaps accurately into place. All you do then is trace around the main magnet with a pencil or other writing utensil, then remove and cut in with a saw or rotary tool. -No more guessing! This kit comes with three target/outlet magnets to accommodate for those pesky 12 foot drywall sheets or other paneling, or simply to speed up work if you have an assistant handy. Works on both 1/2 and 5/8 inch drywall (though keep in mind it is a magnet, so the thinner your material the stronger the connection will be). The best part about it is that this kit will work on virtually ANY paneling, including plywood, tile, siding, particle board, you name it. The only con with this tool is that the electrical boxes have to be open/without outlets, since you need the room for the magnet. So, I imagine this best for new construction, unless you're fine with temporarily removing the outlets to make space. Other than that, this tool is a dream! June 28, 2016
