For nearly 60 years, Stahlin has led the electrical products industry in designing, engineering and manufacturing fiberglass, polycarbonate, and PVC electrical and instrumentation enclosures for diverse interior and exterior applications. They provide the most extensive in-stock and customized line of non-metallic enclosures and accessories, balancing aesthetics with stringent physical property performance standards including NEMA 4X, NEMA 6P, IEC IP66 and IEC IP68 integrity. 

With centralized production, Stahlin is the primary source producer of their key enclosure components. They formulate and blend their own fiberglass composites including patented SolarGuardĀ® for unparalleled UV resistance. Because Stahlin molds their enclosures using the highest processing standards, supported by equally stringent operational efficiency, their Non-Metallic Enclosures offer significant cost savings versus metallic alternatives such as stainless steel; yet provide comparable or superior physical property benefits. RSP Supply is a proud distributor of Stahlin enclosures and accessories.
