Eaton Specification Sheet - ATR, 3/8X72 SS4
72 inch overall length with a 0.375 inch diameter and a 16 inch thread length provides mounting-height flexibility and minimizes on-site cutting. The precise all-threaded design ensures consistent load paths for B-Line strut systems, improving alignment and reducing adjustment time during installation. This configuration is ideal for electrical rooms, data centers, and equipment mezzanines where precise heights and clean aesthetics matter. A 730 lb load rating in steel gives confident support for suspended racks, cable trays, and enclosure mounts. The robust construction resists bending under dynamic loads and helps maintain cable management integrity over time. Using a standard 3/8 inch diameter with a long thread also supports reliable engagement with common nuts and accessories in the Eaton B-Line ecosystem. SC3228 hanger rod stiffener compatibility streamlines assembly, reducing misalignment and rework. This integration enables faster commissioning and repeatable results across multiple mounting points in dense installations. It also simplifies field modifications because the rod length can be kept constant while adjusting positions with the thread length. All-thread rod cut-to-length capability reduces inventory fragmentation by consolidating parts into a single family. This approach lowers procurement lead times, minimizes waste, and simplifies BOM management for retrofit projects. The 16 inch thread length also supports flexible attachments without compromising vertical stability. Documentation and design resources—catalogs and datasheets—are readily accessible, enabling accurate BOM creation and seamless integration with channel nuts, U-bolts, and ATR hardware. The Eaton B-Line catalog ecosystem helps design engineers verify compatibility, plan installations, and avoid part mismatches during procurement. Practical industry insight: standard steel threaded rods like ATR 3/8X72 SS4 are widely used across electrical and data-center infrastructures, delivering predictable performance in compliant installations. Leveraging this part within Eaton's offers reduces supplier risk and accelerates project timelines through proven compatibility.

FAQs
ATR 3/8X72 SS4 is an all-threaded rod designed for Eaton B-Line strut systems. It features a 72 inch overall length, 0.375 inch diameter, and a 16 inch thread length, enabling flexible mounting heights. The rod is steel and rated for up to 730 lb, providing reliable support for racks, enclosures, and cable trays while maintaining alignment with standard nuts and accessories.
The ATR 3/8X72 SS4 carries a 730 lb load rating based on its steel construction and all-thread design. This rating refers to static loading conditions when properly anchored and installed within Eaton B-Line systems. For real-world performance, ensure correct nut engagement, appropriate mounting hardware, and adherence to installation guidelines to avoid overloading any single point.
The provided data lists Certifications as Not Applicable, with no explicit weather or IP rating. Consequently, ATR 3/8X72 SS4 is best suited for indoor electrical, data-center, and mechanical environments where standard steel components are appropriate. For outdoor or harsh environments, consider weather-rated alternatives or protective housings per your facility’s standards.
SC3228 hanger rod stiffeners are designed to work with the ATR all-threaded rod to improve alignment and rigidity. When installing, ensure proper thread engagement and tighten nuts to spec to minimize movement. This combination reduces rework in dense installations and supports consistent performance across multiple mounting points, especially in crowded mechanical rooms.
Eaton provides catalogs and specification sheets for the ATR 3/8X72 SS4, including the B-Line Series Strut Systems Catalog and related sections. Access to these documents helps with accurate BOM creation, compatibility checks with channel nuts, U-bolts, and hanger hardware, and smoother design-in for retrofit projects.
