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.
