Overview
The Appleton T150-M is a Form 35 malleable iron conduit outlet body that serves as a critical pulling fitting in electrical conduit systems. This Type T unilet features a 1-1/2″ hub with 3 hubs and 36 cubic inch capacity, constructed of malleable iron with triple coating (zinc electroplate, chromate, and epoxy powder coat). Designed to connect and change direction of conduit runs while allowing connections for branch runs, this fitting meets NEMA FB-1 enclosure standards and is approved for UL 514A/B and CSA C22.2.
Key Features
- Type T Configuration: Provides a tee hub location with access opening on the side, enabling easy conductor routing and maintenance
- Integral Protection: Smooth, rounded integral bushing in hubs protects conductor insulation
- Thread Integrity: Accurately tapped, tapered FNPT threads provide tight, rigid joints and excellent ground continuity
- Material Strength: Malleable iron construction offers high tensile strength, ductility, and exceptional corrosion and impact resistance
- Surface Mounting: Flat back design ideal for direct mounting against walls or equipment surfaces
- Dual-Purpose Fitting: Serves as both a pulling fitting and permits access to conductors for splicing and maintenance

Typical Applications
Appleton Form 35 conduit outlet bodies are used to connect and change direction of conduit runs, make bends in conduit systems, allow connections for branch runs, and serve as pulling fittings that permit access to conductors for splicing and maintenance. Common installations include:
- Commercial and industrial electrical installations
- Conduit system terminations and direction changes
- Junction points requiring safe conductor access
- Branch circuit connections in power distribution systems
- Hazardous and ordinary location wiring per NEC compliance
