• 4" octagon design - Classic configuration compatible with standard octagon covers and fixtures
• Single row hub arrangement - Accommodates 1/2" and 3/4" conduit connections for flexible system design

Installation Efficiency

• Pre-punched conduit knockouts - Accepts both 1/2" and 3/4" conduit for versatile installation options
• Concrete-tight design - Prevents concrete infiltration during pour operations
• Form-mounting compatibility - Designed for secure attachment to concrete forms and templates
• NEC/CEC compliant construction - Meets electrical code requirements for concrete box installations

Technical Specifications

This octagon concrete box features a 4" x 4" footprint with 2-1/2" depth, providing 29.0 cubic inches of internal capacity. The heavy-gauge steel construction ensures structural integrity during concrete pours while the single-row hub configuration accepts 1/2" and 3/4" trade size conduit connections. The box weighs 0.72 pounds and meets NEC/CEC standards for concrete box installations in ordinary/non-hazardous locations.

Installation Process

1. Position box in concrete form at desired location and secure with appropriate fasteners
2. Remove required knockouts for conduit entries using proper knockout tools
3. Install conduit runs and secure with appropriate connectors before concrete pour
4. Verify box alignment and elevation before concrete placement begins
5. Pour concrete carefully around box, ensuring complete encasement without air pockets
6. Allow concrete to cure completely before installing covers or making electrical connections

Applications

Perfect for:

• Commercial Construction - Office buildings, retail centers, and institutional facilities
• Industrial Facilities - Manufacturing plants, warehouses, and processing centers
• Concrete Slab Installations - Floor-mounted outlets and junction points
• Parking Structures - Lighting and power distribution in concrete parking facilities
• Municipal Projects - Schools, hospitals, and government building electrical systems
• Precast Concrete - Electrical boxes for precast concrete panels and structures
• Foundation Work - Electrical rough-in for concrete foundation systems
• Heavy Construction - Bridge work, tunnels, and infrastructure electrical installations

Concrete Box System Benefits

Concrete boxes provide permanent, tamper-resistant electrical connections that become an integral part of the building structure. Unlike surface-mounted alternatives, concrete boxes offer superior protection against physical damage, environmental conditions, and unauthorized access. The embedded installation creates a clean, professional appearance while providing reliable electrical connections that last for decades.

Why Choose Steel Construction?

Steel concrete boxes offer superior strength and durability compared to plastic alternatives, making them ideal for heavy-duty commercial and industrial applications. The robust steel construction withstands the pressures of concrete placement while providing excellent grounding continuity and long-term reliability. Eaton Crouse-Hinds steel boxes are engineered to professional standards, ensuring consistent performance in demanding concrete construction environments.
