Eaton Specification Sheet - CB3 HDG
Material and finish deliver exceptional durability: the malleable iron construction with a hot dip galvanized coating provides corrosion resistance in non-hazardous industrial settings, extending service life and reducing replacement costs. This translates to lower total cost of ownership and less downtime during outdoor or damp installations, where exposure to moisture is common. Conduit compatibility enhances flexibility: designed for EMT and rigid/IMC systems at a 1" trade size, enabling a single part to support multiple raceway configurations, simplifying procurement and inventory management on busy jobsites. The clampback/spacer design improves alignment and installation speed: fastens securely to conduit while maintaining proper spacing, reducing rework and easing future maintenance. Compact dimensions and light weight support cleaner, lower-profile installations in crowded panels and conduit runs, improving airflow and wiring organization while cutting labor costs. Code compliance ensures confidence: NEC/CEC standards alignment and ordinary location rating provide clear pathways to permit approval and safer installations, helping projects meet regulatory timelines. Cross-border reliability is enhanced by UL Canadian certification for EMT, enabling smooth procurement for multi-national facilities and reducing qualification risk. The overall system offers a practical, long-term solution that aligns with industry best practices for conduit supports.

FAQs
To install the CB3 HDG clampback/spacer, position the spacer behind the conduit and align the clampback with the conduit groove. Secure with appropriate fasteners to ensure a tight, vibration-resistant hold. Ensure the 1" trade size matches the conduit and verify the fitment against NEC/CEC requirements for ordinary locations. This design enables quick adjustments and minimizes alignment errors during routing.
Key specs include a 1" trade size for EMT and Rigid/IMC, malleable iron material, hot dip galvanized finish, dimensions of 2.31 in length, 1.25 in width, and 0.56 in height, and a weight of 0.16 lb. Catalog number is CB3 HDG, with UPC 662277038737, and it is listed for ordinary/non-hazardous locations under NEC/CEC standards.
Yes. The CB3 HDG clampback/spacer is specified for Ordinary/Non-Hazardous Locations and carries NEC/CEC standards compliance, making it appropriate for standard commercial and industrial installations. The UL Canadian EMT certification further supports cross-border use and regulatory acceptance in multi-site projects.
Absolutely. The CB3 HDG is designed for EMT and Rigid/IMC conduits, offering a versatile 1" solution that simplifies stocking and installation across diverse raceway systems. Itsmal leable iron construction and galvanization ensure durable performance across these conduit types through typical industrial environments.
The hot-dip galvanized finish provides superior corrosion resistance, extending the life of clamps in moisture-prone or outdoor settings. This reduces replacement frequency, minimizes maintenance visits, and improves long-term reliability in harsh industrial environments, delivering lower lifecycle costs and greater system uptime.
