Overview
The Appleton C150-M Form 35 conduit outlet body is a malleable iron Type C unilet designed for use with rigid steel, rigid aluminum, IMC, and EMT conduit systems. This lot includes two units, each rated at 35.3 cubic inches capacity with 1-1/2″ hub threads. The Form 35 designation indicates malleable iron construction with high tensile strength and ductility, making these conduit bodies ideal for standard industrial conduit applications requiring secure connections and reliable conductor access.
Key Features
- Type C Configuration: Serves as pulling fittings, allows bends in conduit systems, provides openings for splicing, connects and changes direction of conduit runs, allows connections for branch runs, and permits access to conductors for maintenance
- Malleable Iron Construction: Form 35 malleable iron with high tensile strength and ductility
- Smooth Bushings: Smooth, rounded integral bushings in hubs protect conductor insulation
- Tight Thread Connections: Accurately tapped, tapered threads for tight, rigid joints and excellent ground continuity
- Triple-Coated Finish: Triple coated for high corrosion resistance, high impact and shock resistance
- NEMA FB-1 Enclosure: Meets NEMA standards for electrical enclosures and outlet bodies
