Calculated Industries 8105 Blind Mark Drywall Box Locator Kit – 3 Magnets & Locator

The Calculated Industries 8105 Blind Mark Drywall Electrical Box Locator Tool accelerates wall box placement without traditional measuring. Designed around three powerful rare‑earth magnets, it helps you locate and mark hidden electrical boxes through drywall, paneling, and similar materials so you can cut openings with greater confidence.

How Blind Mark helps your project

By placing the magnet targets inside the outlet boxes and then applying light pressure to the drywall, you give the locator a guide to reveal the precise mark points behind the wall. This approach reduces guesswork and supports a smoother workflow from start to finish.

Real‑world advantages include faster setup, less lifting of heavy drywall, and fewer chances of mis‑cuts. The system is designed to save time on drywall installations while keeping the process simple and straightforward. You can work on several boxes at once, then mark and cut in a single, efficient pass.

Key benefits you may notice

• No measuring required for locating outlets or switch boxes behind walls.
• Magnetic targets transmit through drywall and paneling for quick, accurate centering.
• Reduces lifting effort since you mark once and cut, often without repeated sheet handling.
• Works across multiple materials including drywall, plywood, paneling, and cement board.
• Includes three targets and a rugged storage case to keep everything organized between jobs.

What’s included and how to use

• Three high‑strength rare‑earth magnets placed inside outlet boxes to locate centers behind walls.
• A precision locator to translate magnet positions into wall marks for cutouts.
• A rugged storage case to protect the targets and locator when not in use.

Whether you’re installing drywall, paneling, or other wall finishes, Blind Mark guides you to clean, well‑fitted openings. It’s designed to be a practical tool for both pros and DIY enthusiasts, helping you achieve precise results while keeping the process approachable. While not a guarantee of outcome, the system emphasizes accuracy and efficiency by design, supporting faster project progression with fewer unexpected reworks.

Note: This kit is compatible with a range of common build materials and is best used as part of a careful planning process. If you want to streamline drywall work and reduce the need for patching or oversized plates, Blind Mark offers a practical method to help you mark and cut with fewer steps.
