• Ordinary Location Rated - Suitable for standard commercial and industrial environments
• Grounding Continuity - Non-insulated design ensures proper equipment grounding throughout the system

Technical Specifications

This CPR series compression connector accommodates 1-1/4" trade size rigid and IMC conduit with precise dimensional tolerances. The malleable iron construction provides exceptional tensile strength while maintaining the ductility needed for reliable long-term performance. Measuring 2.38" in width and height with a 2" depth, this connector weighs 0.64 pounds, reflecting its robust construction. The straight configuration enables direct connections in tight spaces while maintaining full electrical continuity through the non-insulated design.

Installation Process

1. Verify conduit end is cut square and deburred to prevent damage to connector threads
2. Insert conduit fully into the connector body until it reaches the internal stop
3. Hand-tighten the compression nut to ensure proper seating of the conduit
4. Use appropriate wrenches to tighten the compression mechanism to manufacturer specifications
5. Verify secure connection by checking that conduit cannot be withdrawn from connector
6. Test grounding continuity across the connection to ensure proper electrical path

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, and healthcare facilities requiring reliable conduit connections
• Industrial Facilities - Manufacturing plants, processing facilities, and warehouses with demanding electrical systems
• Equipment Connections - Motor control centers, switchgear, and distribution panels requiring secure conduit terminations
• Electrical Panels - Main distribution panels, sub-panels, and load centers in commercial installations
• Conduit Extensions - Connecting rigid or IMC conduit runs to electrical enclosures and junction boxes
• Municipal Infrastructure - Schools, government buildings, and public facilities requiring code-compliant installations
• Heavy-Duty Applications - Installations subject to vibration, thermal cycling, or mechanical stress
• Grounding Systems - Applications requiring continuous grounding path through conduit connections

Compression Connector System Benefits

Compression connectors offer significant advantages over threaded connections in professional electrical installations. The compression mechanism creates a mechanical bond that resists loosening from vibration and thermal cycling, while eliminating the need for field threading that can weaken conduit walls. This results in faster installation times, more reliable connections, and reduced maintenance requirements over the system's lifetime.

Why Choose Malleable Iron Construction?

Malleable iron provides the ideal combination of strength and ductility for demanding electrical connector applications. Unlike brittle cast iron or standard steel, malleable iron can withstand impact and stress without cracking, while offering superior corrosion resistance and dimensional stability. This makes it the preferred material choice for contractors who demand long-term reliability and performance in their electrical installations, backed by Eaton Crouse-Hinds' century of electrical innovation and engineering excellence.
