Eaton CB1 HDG Clampback/Spacer - Hot Dip Galvanized
Part Number: CB1 HDG
Quick Summary
CB1 HDG clampback/spacer from Eaton securely supports EMT and rigid/IMC conduit in industrial and commercial electrical installations. This hardware addresses corrosion-prone environments and tight spaces where clamps can loosen or fail, causing downtime. It adopts a hot dip galvanized finish for durability and is forged from malleable iron to resist vibration and load changes. The product aligns with NEC/CEC standards for ordinary locations and carries relevant certifications for EMT hardware used in Canada, helping streamline compliance across projects. For procurement, the compact 2 in length with a 1/2 in trade size and 0.5 in height reduces part count while delivering reliable conduit support in demanding installations.

Material and finish enable durable, corrosion-resistant performance in harsh environments. The malleable iron construction with a hot dip galvanized coating resists moisture and salt exposure, reducing maintenance and replacement costs. This hardware also withstands vibration and dynamic loads common in industrial settings, maintaining conduit alignment over time. Compatibility with EMT and Rigid/IMC conduits across a 1/2 inch trade size minimizes parts diversity, simplifying stocking and on-site assembly while speeding up installation. The compact 2 inch length, 1 inch width, and 0.5 inch height fit tight spaces without compromising strength, enabling use in crowded panels and overhead runs. NEC/CEC compliance and UL Canada references for EMT hardware help ensure regulatory acceptance across North America, reducing project risk for multi-site deployments. Clampback/spacer design supports fast mounting and repeatable conduit positioning for consistent, high-quality installations.

FAQs
CB1 HDG is designed for EMT and Rigid/IMC conduits with a 1/2 inch trade size. For installation, mount the clampback/spacer to a suitable support surface, seat the conduit fully into the clamp, and secure with the appropriate fasteners. Refer to Eaton’s CB1 HDG specification sheet for exact mounting guidelines and torque recommendations to ensure reliable performance and code compliance.
The device measures 2 inches in length, 1 inch in width, and 0.5 inches in height, with a weight of 0.08 lb. It supports a 1/2 inch trade size conduit and is constructed from malleable iron with a hot-dip galvanized finish. These compact, lightweight dimensions enable easy handling in tight spaces while maintaining robust conduit support and vibration resistance.
Yes. The CB1 HDG is specified for Ordinary/Non-Hazardous Locations and complies with NEC/CEC standards, making it suitable for general electrical installations in commercial and light-to-medium industrial environments. Its durable finish and reliable clampback/spacer design help ensure consistent performance across typical facility layouts without specialized mounting conditions.
CB1 HDG adheres to NEC/CEC standards for ordinary locations and references UL Canada certifications for EMT hardware, contributing to regulatory acceptance in North American projects. This dual alignment reduces compliance risk, accelerates approvals, and simplifies cross-border procurement for multi-site facilities that require proven, code-compliant conduit support hardware.
The hot-dip galvanized finish delivers superior corrosion resistance, extending service life in damp or outdoor environments and reducing maintenance cycles. Although initial cost may be higher than uncoated options, the longer lifespan, lower replacement frequency, and fewer maintenance interventions translate to lower total cost of ownership over the hardware’s lifecycle, especially in harsh industrial settings.
