• Steel Construction - Durable material withstands installation forces and provides long-term mechanical integrity
• 1-1/4" Trade Size - Accommodates standard EMT conduit for versatile system compatibility

Electrical Safety & Performance

• Insulated Throat Design - Protects conductors from sharp edges during wire pulling and prevents insulation damage
• NEC/CEC Compliant - Meets national electrical code requirements for safe installation practices
• Straight Configuration - Direct conduit-to-enclosure connection minimizes installation complexity
• Professional Grade Quality - Engineered to Crouse-Hinds standards for decades of reliable service

Technical Specifications

This connector features 1-1/4" trade size compatibility with standard EMT conduit systems. The steel construction provides excellent durability while the insulated throat design protects conductor insulation during installation. Dual set screws ensure secure mechanical connection, while precision threading allows smooth engagement with electrical enclosures. The straight configuration measures 2.25" in length with 1.75" width and height dimensions, weighing 0.46 pounds for easy handling during installation.

Installation Process

1. Verify EMT conduit end is cut square and deburred to prevent conductor damage
2. Insert conduit fully into connector until it contacts the internal shoulder
3. Tighten both set screws alternately to ensure even pressure distribution
4. Thread connector into electrical enclosure knockout opening
5. Tighten securely using appropriate wrench size for locknut engagement
6. Verify mechanical connection integrity before pulling conductors

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, and healthcare facilities requiring reliable conduit connections
• Industrial Facilities - Manufacturing plants, processing centers, and warehouse electrical distribution systems
• Panel Connections - Electrical panels, motor control centers, and switchgear installations
• Equipment Hookups - HVAC units, machinery connections, and process equipment electrical feeds
• Renovation Projects - Electrical system upgrades and additions in existing buildings
• Municipal Infrastructure - Schools, government buildings, and public facility electrical systems
• Data Centers - Server room electrical distribution and equipment connections
• Healthcare Facilities - Hospital electrical systems requiring reliable, code-compliant connections

EMT Set Screw Connector System Benefits

Set screw connectors offer superior installation speed compared to compression fittings while maintaining excellent mechanical strength. The dual screw design distributes clamping force evenly around the conduit circumference, preventing deformation while ensuring secure retention. This makes them ideal for applications where conduit may experience vibration or thermal cycling that could loosen single-point connections.

Why Choose Insulated Throat Design?

The insulated throat protects conductor insulation from damage during wire pulling operations, reducing the risk of ground faults and electrical failures. This feature is particularly valuable in commercial installations where conductor replacement costs are high and system reliability is critical. Combined with Crouse-Hinds' century of electrical innovation, this connector delivers the professional-grade performance that electrical contractors trust for demanding applications.
