FAQs
ATR 7/8X144 ZN is designed for Eaton B-Line support structures and pairs with common B-Line components such as channel nuts and hardware, including compatibility with 98 and 98B rod stiffeners for enhanced rigidity in long-span suspensions. Its 144 inch length minimizes field splicing, while the 0.875 inch diameter and 9 inch thread length ensure reliable engagement with standard fasteners in channel and rack configurations.
Key specs include a 144 inch length, 0.875 inch diameter, 9 inch thread length, steel construction, zinc finish, and a 4480 lb load rating. The component is designed to suspend equipment within Eaton B-Line channel systems, providing strong load-bearing capacity while remaining compatible with typical nuts, anchors, and rod stiffeners used in industrial installations.
Yes. This rod is specifically noted as Used with (98 & 98B) rod stiffeners, which improves system rigidity and reduces sag in long spans. The zinc finish offers corrosion resistance suitable for indoor electrical and mechanical installations; for outdoor or highly corrosive environments, consider alternative finishes or protective coatings and verify project requirements with your cages and enclosures standards.
When using ATR 7/8X144 ZN, plan for full-thread engagement with compatible nuts and hardware, ensuring proper clearance for the 9 inch thread length. Check compatibility with other B-Line components and stiffeners, optimize mounting points to maintain axial alignment, and confirm that the load distribution matches design calculations to prevent uneven stress on channel systems.
The ROI comes from reduced field fabrication, fewer joints, and faster installation due to pre-cut, long-length rod and standardized hardware compatibility. The high load rating supports heavier equipment with minimal risk of failure, while zinc protection prolongs service life in indoor environments. Overall, projects benefit from lower labor costs and higher installation reliability.
