Eaton ATR, 3/8X144 ZN All Threaded Rod - 730 lb load cap
Part Number: ATR, 3/8X144 ZN
Quick Summary
The Eaton B-Line Series all threaded rod is a versatile mounting element for electrical enclosures and support structures. Installations often stall due to variable thread lengths, misalignment, and uncertain load ratings, which drive project delays. Certifications are Not Applicable; however, the rod’s 144 in length, 16 in thread length, and 730 lb load capacity satisfy common industrial design criteria. Its steel construction and compatibility with Eaton’s B-Line components simplify procurement and field assembly, reducing inventory complexity and install time. Designed to work with SC3228 hanger rod stiffeners and standard strut systems, it supports safer, faster, and more cost-effective installations.

FAQs
ATR, 3/8X144 ZN is designed for straightforward integration with Eaton B-Line components. Verify the 144 inch overall length aligns with your support spans and use the 16 inch thread length to engage compatible nuts and fittings. When pairing with SC3228 hanger rod stiffeners, ensure proper alignment and spacing to maximize rigidity and minimize sway during operation.
Key specifications include a 144 inch overall length, 0.375 inch diameter, 16 inch thread length, and a 730 pound load capacity, all in a steel construction with a zinc finish. The catalog number is ATR, 3/8X144 ZN, and it is UPC 781011690373. These dimensions define its suitability for long-span mounting in B-Line systems.
Yes, the 144 inch length and 0.375 inch diameter all-threaded rod are well-suited for ceiling suspension of light-to-moderate equipment, electrical panels, and conduit runs in industrial settings. The 730 lb load rating provides a safety margin for typical suspended assemblies, especially when used in conjunction with SC3228 stiffeners and compatible strut hardware.
Certifications for this specific part are listed as Not Applicable. When designing a compliant system, verify project requirements against your facility’s standards and consult Eaton’s catalogs for applicable certifications on integrated components. Always coordinate with your design engineer to ensure the entire assembly meets local codes and safety guidelines.
Maintenance considerations focus on inspection for corrosion, corrosion protection from the zinc finish, and checking thread engagement at connection points. Replace any rod showing signs of significant wear, deformation, or corrosion. Because this is a long, steel, zinc-coated rod, periodic inspection in damp or harsh environments is recommended to preserve structural integrity.
