Perfect for first-time DIYs or the experienced handyperson replacing or covering existing drywall, the plug mark electrical outlet locator uses powerful rare-earth magnets to help you accurately locate and cut access holes for existing wired sockets in drywall, sheetrock, paneling and other materials with no measuring required. Eliminates costly measuring errors and drastically improves your project's productivity. The perfect addition to your #8105 Blind Mark set when doing rehabilitation and replacement projects! TWICE AS ACCURATE - say goodbye to mis-measured and mis-cut drywall openings or having to patch or buy oversize plate covers. With Plug Mark you'll cut perfect openings every time. HANG IT ONCE, CUT IT RIGHT - while other drywall locator methods require you to lift and lower heavy drywall sheets multiple times to mark, cut, then install, with the Plug Mark you simply put it up once, cut the hole and you're done. HALF THE LIFTING - because you only lift the drywall once to install it you not only finish in half the time but with much less fatigue or chance of injury or damage to fragile drywall. 3 FOOLPROOF STEPS - snap the Plug Mark targets into your existing electrical sockets, install the drywall, find the targets and cut them out. Done! MULTIPLE MATERIALS - the versatile Plug Mark Works on drywall, plywood, particle board, laminated flooring, masonite, exterior siding, cement board, tile backsplashes, slate and more! COMES COMPLETE - this handy kit includes 2 targets that plug into existing wired electrical sockets and one Blind Mark locator. Why make replacement drywall installation harder than it has to be let? Let Plug Mark take the guesswork and the grunt work out of electrical box cutouts. Click the add to cart button now. Review: A HUGE timesave, easy to use, and made the project so much simpler to accomplish - Wish you could give more then 5 stars on this product. This is a REALLY cool product. I just remodeled my basement, and had to cut about 300 outlets (ok, 9, but thats still a pain!). The drywall had been up for years with outlets, but we had decided to panel. So, I was looking at having to carefully measure and cut each, and hope I had everything lined up perfect (which I am NOT good at, by the way). I happened across an article about this product in a woodworkers blog, and so ordered this to give it a try ($20 was worth the effort if it even kind of worked). Opened it, grabbed my rotozip, and less then 1 1/2 hours later I had the whole room paneled and cover plates reinstalled.. Pop the target into the outlet, hang the paneling, find the target with the box piece, trace around it, and zip it out. It cuts JUST outside the edge of the box if you follow your lines closely. Take your time following the lines, and your existing plates work great! WARNING!!! From experience (and cutting through one of the targets): MAKE SURE YOU TWIST IT ONCE CONNECTED!!! You want to make dang sure that you caught both magnets, not just one. I was getting cocky near the end and didn't check one. OOPS! These magnets are strong, so once you "find" the target and the magnet grabs, just twist it left and right. You will quickly be able to tell if both magnets grabbed, or if you are just floating on one. If you can easily twist it, keep turning it until the other magnet lines up and it snaps into place, then trace and cut!

Could be better *by C***B on May 6, 2026* Handy. My only suggestion would be lose the two magnet set up and go with a bar magnet. Once the wall covering goes on, if you catch one magnet and miss the other, you're half a box off. ## Frequently Bought Together - Calculated Industries 8120 Plug Mark Drywall Electrical Box Cutout Locator for Existing Electrical Outlets in Rehabilitation and Replacement Work, Red - Calculated Industries 8105 Blind Mark Drywall Electrical Box Locator Tool – Powerful Rare-Earth Magnetic Targets (3) and Locator Kit - Calculated Industries 8115 Multi Mark Drywall Cutout Locator Tool – Powerful Rare-Earth Magnetic Targets (2) and Locator Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/30350703-plug-mark-model-8120](https://www.desertcart.tn/products/30350703-plug-mark-model-8120) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-09*
