Eaton ATR 3/8X144 SS4 All Threaded Rod - 16 in Thread Length

ATR, 3/8X144 SS4 all threaded rod is a robust steel rod designed for Eaton B-Line strut systems, delivering reliable performance in demanding industrial spaces where vibration, temperature variation, and frequent reconfiguration are the norm. Its all-threaded configuration eliminates mis-matched hardware from the bill of materials, simplifying procurement and on-site assembly. The 144 in length, 0.375 in diameter, a 16 in thread length, and a 730 lb load capacity enable safe support for moderate-to-heavy fixtures such as lighting, conduit, and equipment mounts in service corridors and utility rooms. The 16 inch thread length is a common standard across Eaton strut system installations, ensuring consistent mounting heights across multiple projects. Primary applications span overhead ceilings, cable trays, lighting and mechanical mounting, where precise length and secure engagement matter for long service life; this rod serves as a universal core component for both new installations and retrofit projects, aligning with legacy B-Line channel systems and modern modular supports. It suits indoor environments with standard steel finishes and typical factory or data-center spaces. The all threaded design eliminates loose nuts and minimizes field cutting, accelerating installation while reducing procurement complexity and carrying lower inventory costs; engineers and installers appreciate straight-through length options that adapt to irregular ceilings and drilled anchors without field machining. Compatibility with SC3228 hanger rod stiffener enhances rigidity in high-vibration environments and supports compliant, code-ready installations; this feature improves service life in warehouses, data centers, and manufacturing floors where sudden loads and seismic conditions can occur. The combination with B-Line strut systems and channel nuts offers flexible mounting geometry for complex loads. Comprehensive catalogs, installation guidance, and specification sheets from Eaton streamline design validation, permitting faster quoting, easier material traceability, and safer, auditable builds across multi-site projects; procurement teams benefit from standardized components that reduce variance in the field and simplify maintenance planning. The availability of technical datasheets and installation videos supports training for field crews and reduces start-up downtime.
