• 105°C Temperature Rating - Handles high-temperature applications safely and reliably
• 3" Trade Size - Perfect for large conductor bundles and high-amperage applications

Professional-Grade Construction

• Malleable Iron Material - Stronger than steel construction for maximum durability and impact resistance
• Precision Threading - Ensures secure, vibration-resistant connections to conduit systems
• Corrosion-Resistant Finish - Long-lasting protection in demanding industrial environments
• NEC/CEC Compliant - Meets all applicable electrical code requirements

Installation Efficiency

• Standard Threading - Compatible with all rigid and IMC conduit systems
• Compact Profile - Fits in tight spaces while providing full wire protection
• Easy Installation - Threads quickly onto conduit ends for fast, professional installations

Technical Specifications

This throat bushing features a 3" trade size with standard NPT threading compatible with rigid and IMC conduit systems. The malleable iron construction provides superior strength compared to steel alternatives, while the insulated throat design protects conductor insulation up to 105°C. The threaded connection ensures secure attachment to conduit ends, and the compact 4" length and 1" height profile fits standard electrical enclosures and junction boxes.

Installation Process

1. Verify conduit end is properly reamed and deburred to prevent wire damage
2. Apply appropriate thread compound to conduit threads for weather-tight seal
3. Thread bushing onto conduit end, ensuring full engagement of threads
4. Tighten securely using appropriate wrench, avoiding over-tightening
5. Verify smooth interior surface before pulling conductors through
6. Install conductors carefully, taking advantage of the insulated throat protection

Applications

Perfect for:

• Industrial Control Panels - Motor control centers, switchgear, and distribution panels
• Commercial Buildings - Office complexes, retail centers, and institutional facilities
• Manufacturing Facilities - Production equipment connections and process control systems
• Heavy-Duty Applications - High-amperage circuits and large conductor installations
• Outdoor Installations - Weather-exposed conduit terminations requiring wire protection
• Municipal Infrastructure - Schools, hospitals, and government building electrical systems
• Equipment Connections - Large motor terminations and transformer connections
• Service Entrance Applications - Main electrical service conduit terminations

Throat Bushing System Benefits

Throat bushings provide essential wire protection that standard conduit connections cannot offer. The insulated design prevents conductor damage during installation and protects against vibration-induced wear over time. This is particularly critical in 3" applications where large, expensive conductors require maximum protection. The threaded design ensures the bushing stays securely in place, unlike push-in alternatives that can work loose.

Why Choose Malleable Iron Construction?

Malleable iron offers superior strength and durability compared to steel or aluminum alternatives, making it ideal for heavy-duty electrical applications. This material resists cracking under stress and provides excellent thread integrity for long-term reliability. Combined with Eaton Crouse-Hinds' century of electrical innovation, this throat bushing delivers the professional-grade performance that electrical contractors trust for critical installations.
