TWICE AS ACCURATE ; no more mis-measured and mis-cut drywall openings or having to patch mis-cuts or need to buy oversize plate covers. With Blind Mark you ;ll cut perfect openings every time.

Rugged storage case keeps the high quality plastic targets and locator organized and protected between projects. Why make drywall installation harder than it has to be?

The gang box sticks out a half inch from the studs. How do you install the drywall without first cutting the hole?** A: the box is only 1/4inch past studs. not 1/2. the drywall will just float over the box. so when you hang the drywall, only use 3 or 4 screws- just enough to hold it in place. then use the magnet to find your box, and cut it out. then finish screwing in the drywall. This tool works great. i just did an entire house with absolutly zero problems **Q: Will it work through osb** A: On the back of the box it says the following:"Works on drywall, plywood, particle board, laminated flooring, Masonite, exterior siding, cement board, tile, and slate."Thanks,General Tool **Q: What tool are you using to cut the sheet rock i feel like a dremel would cut right through the metal wire being used to hold the magnet to the box** A: Commercial drywallers use drywall routers/Rotozips(large Dremels spinning at 9000rpm). But you can use anything. You will not come in contact with the inside of the box, maybe the tabs of the outside of box. The outside marker magnet is larger than the inside box magnet and spring tabs. If you are worried about even touching the outside tabs of an electrical box, set your depth on the bit to that of the drywall. **Q: Does the electrical box have to be empty** A: With this kit, yes the box would need to be empty, but they also make something called a plug mark that plugs into an existing wall outlet. Of course that doesn't work for light switches. But there is always lipstick for those.http://www.amazon.com/gp/product/B00XUY9FB8?psc=1&redirect=true&ref_=od_aui_detailpages02 ## Frequently Bought Together - 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 - Upgrade 2 Pcs Square Slot Cutter Compatible for Dewalt 20V & Milwukee M18 Oscillating Multi-Tool to Cut-in Single Gang Wall Boxes,Outlet Cutter for Drywall,Efficient Carving Tool,Black --- ## 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.at/products/15936543-blind-mark-xl-model-8105](https://www.desertcart.at/products/15936543-blind-mark-xl-model-8105) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-15*
