Stanley 47-400 Stud Finder

Product Description

The STANLEY 47-400 is a stud finder designed for locating wall studs behind drywall and other common wall surfaces. It gives electricians, drywall installers, carpenters, and general contractors a fast, reliable way to identify framing members before cutting, drilling, or fastening. The unit ships as a single piece and weighs approximately 0.04 pounds, making it a lightweight handheld tool suited for frequent use on the job site or in residential service work. It is a standard addition to a trade professional's diagnostic toolkit when working on wall-mounted installations or any task requiring knowledge of framing location.

The 47-400 is appropriate for residential and light commercial applications where locating studs through finished wall surfaces is required. Typical use cases include mounting electrical panels, running conduit, installing wall-mounted fixtures, hanging heavy loads, and any framing-adjacent task where knowing stud position reduces rework and prevents damage to wall assemblies. It is sold and counted individually.

Installation Notes

Stud finders are used by electricians, carpenters, and general contractors before cutting, drilling, or fastening into finished walls. Calibrate the tool against a known clear section of wall before scanning, following the manufacturer's calibration procedure. Always verify stud location with a secondary check before cutting into any wall cavity that may contain electrical wiring, plumbing, or gas lines.
