To cut a hole in drywall for an electrical box, you measure X, then measure Y, transfer those to the drywall, and cut out as needed with a saw or rotary cutter. It’s simple in theory — but in practice there’s a lot of room for error, especially if you’re a DIYer for whom this isn’t your regular job. The Blind Mark Electrical Cutout Tool system, with its two-part magnetic template, takes out the guesswork and helps you avoid costly mistakes.
The Blind Mark kit comes with three targets and one target locater template. Before the drywall goes up, you place the targets inside the electrical boxes. After the board is secured, slide the target finder across the drywall until the magnets lock together. Mark a line around the template, cut out a hole for the future switch or outlet, and remove the target. It simplifies the multi-step process and helps eliminate mistakes. The kit sells for $25 at the official site as well as at Lowe’s and Home Depot.
