Greenfield Manufacturing 948-18 Stud Protector Plate – 16 Gauge, 1.5" x 18", 16-Hole

The Greenfield Manufacturing 948-18 Stud Protector Plate is a 16-gauge steel protective plate designed for use in structural framing to shield concealed electrical wiring, plumbing, and mechanical lines from penetration by fasteners. Engineered for compliance with building and electrical codes, this plate provides mechanical protection where pipes or cables pass through or within framing members. The precision-punched holes allow secure fastening to wood or metal studs while maintaining alignment and load-bearing integrity across framing assemblies.

Technical Application

The GFM 948-18 Stud Protector Plate is intended for installation over bored or notched framing members where mechanical protection is required by code. Fabricated from 16-gauge steel, the plate resists penetration from nails, screws, and fasteners, safeguarding concealed wiring or piping located within 1-1/4" of the stud face. The 18-inch length and 1.5-inch width allow continuous coverage across standard stud faces or along vertical runs. The 16 pre-punched 0.19-inch holes provide multiple fastening points for secure attachment and alignment. The steel construction ensures consistent rigidity and code-compliant impact resistance, while the corrosion-resistant surface finish supports use in interior framing applications.

Installation Notes

Install the plate directly over notches or bored holes in framing members where wires or pipes pass within 1-1/4" of the nailing surface. Secure using nails or screws through the pre-punched holes. Ensure the plate fully covers all penetrations to meet code requirements for mechanical protection. When used in series, overlap or align plates to maintain continuous coverage across the protected section. Avoid over-driving fasteners that could distort the plate or compromise coverage.
