Eaton Specification Sheet - ATR, 1/4X144 ZN
Feature: 144 inch length and 0.25 inch diameter rod provide a long-span suspension option that reduces the number of connections and potential failure points. Business Impact: lowers installation time and improves structural reliability on vertical runs and overhead supports. Application: ideal for electrical raceways, lighting supports, and equipment hangs in commercial buildings.Feature: 20 inch thread length offers precise adjustment and secure anchoring. Business Impact: enables quick leveling and load sharing without reworking installed hardware. Application: mounting large electrical enclosures and mechanical equipment where exact positioning matters.Feature: Steel construction with zinc finish (ZN) delivers durable corrosion resistance in typical indoor environments. Business Impact: extends service life and reduces maintenance cycles, lowering lifecycle costs. Application: warehouse, data center, and manufacturing floors where exposure to humidity or cleaners is common.Feature: 240 lb load capacity provides a clear safety margin for suspended components. Business Impact: supports heavy equipment with predictable performance and minimal sag. Application: supports ceiling-mounted equipment, fans, and service rails in strut-based systems.Feature: Compatibility with Eaton B-Line strut systems and channel hardware improves installation efficiency. Business Impact: reduces part proliferation and simplifies sourcing, improving project timelines. Application: any project using Eaton channel nuts, strut channels, and accessories for a cohesive, code-compliant install.Feature: Not Applicable certifications; the product aligns with standard steel rod specs and Eaton’s internal quality processes. Business Impact: streamlines procurement for non-regulated settings while encouraging verification for projects with strict certification needs. Application: industrial and commercial installations where standard hardware is acceptable and project requirements are documented.

FAQs
The ATR 1/4X144 ZN rod is designed for use with Eaton B-Line strut channels, nuts, and anchors. Start by placing channel nuts on the strut, thread the rod through the nut, and adjust to the desired length using the 20 in thread length as a reference. Secure with appropriate washers and nuts, then tighten to spec. This integration minimizes hardware misfits and streamlines procurement on typical electrical or mechanical install projects.
The rod is rated to 240 lb load capacity, providing a clear safety margin for standard suspended components such as panels, lights, and small equipment. For higher loads, consult the installation diagram and Eaton datasheet to confirm whether multiple rods or additional supports are required, ensuring continued compliance with project safety standards.
The zinc-plated steel rod (ZN) is optimized for indoor, non-corrosive environments. While it offers improved corrosion resistance over raw steel, for outdoor or highly humid installations you may need additional protective finishes or alternative materials. Always verify environmental conditions against Eaton’s specifications for longevity and warranty expectations.
This all threaded rod excels in overhead electrical supports, equipment mounting, and between-strut connections within Eaton B-Line channel systems. Its long 144 inch length suits extended runs, while the 0.25 inch diameter provides a balance of strength and flexibility for retrofit and new-build projects alike.
Using a standardized all threaded rod like ATR reduces inventory complexity and speeds up installation with predictable performance. The steel construction and zinc finish minimize maintenance in typical indoor facilities, translating to lower labor costs, fewer callbacks, and faster project completion—especially when paired with compatible Eaton hardware.
