• Precision threading - Smooth installation with consistent fit on rigid and IMC conduit
• Corrosion-resistant finish - Long-term performance in demanding environments
• NEC/CEC compliant - Meets code requirements for conductor protection in conduit systems

Installation Efficiency

• Standard 3/4" trade size - Compatible with common conduit sizes in commercial installations
• Compact profile - Minimal space requirements in crowded electrical enclosures
• Easy identification - Clear size marking for quick field verification

Technical Specifications

This throat bushing features 3/4" trade size threading compatible with rigid steel and IMC conduit systems. The malleable iron construction provides exceptional strength-to-weight ratio, while the insulated throat design protects conductors rated up to 105°C. Dimensions include 1.25" length and depth with 0.69" height, weighing just 0.04 pounds for easy handling. The threaded design ensures secure installation in electrical panels, junction boxes, and equipment enclosures.

Installation Process

1. Verify conduit end is properly reamed and deburred to prevent conductor damage
2. Thread the bushing onto the conduit end by hand until finger-tight
3. Use appropriate tools to tighten securely without over-torquing the malleable iron threads
4. Verify the insulated throat is properly positioned to protect conductor entry
5. Install conduit assembly into electrical enclosure or equipment
6. Pull conductors through the protected throat opening, ensuring smooth entry

Applications

Perfect for:

• Commercial electrical panels - Distribution panels, switchboards, and motor control centers
• Industrial equipment connections - Machinery, process equipment, and control systems
• Junction box installations - Pull boxes, splice enclosures, and equipment terminations
• Conduit system terminations - Rigid steel and IMC conduit entries into enclosures
• High-temperature applications - Areas where conductors may experience elevated temperatures
• Code compliance projects - Installations requiring NEC/CEC conductor protection
• Retrofit installations - Upgrading existing conduit systems with proper wire protection
• Municipal infrastructure - Schools, hospitals, government buildings, and public facilities

Throat Bushing System Benefits

Throat bushings are essential components in professional electrical installations, providing critical conductor protection that prevents costly wire damage and ensures long-term system reliability. Unlike unprotected conduit entries, insulated throat bushings eliminate sharp edges that can nick or cut conductor insulation during installation or thermal expansion cycles. This protection is especially important in commercial and industrial applications where conductor replacement costs and downtime can be significant.
