Eaton Specification Sheet - ATR, 5/16X72 ZN
All threaded rod design with 72 in height and 0.31 in diameter in steel with a zinc finish provides robust load capacity and corrosion resistance. This translates to fewer replacements and longer service life in overhead runs, directly reducing maintenance cycles. It is suited for suspending electrical enclosures, cable trays, and mechanical equipment in industrial facilities, improving system rigidity and alignment. The 18 in thread length enables straightforward length adjustments without additional couplings, reducing parts count and installation time while maintaining secure connections with standard nuts and washers. Use with SC3228 hanger rod stiffeners for added rigidity and cleaner layouts, particularly in crowded ceiling spaces. Compatibility with Eaton B-Line strut systems ensures streamlined procurement and interchangeability across project scopes, supporting scalable, repeatable installations. Zinc finish and steel construction offer cost savings through durability and lower replacement needs, while the all threaded rod cut to length capability minimizes waste and simplifies field layouts.

FAQs
ATR 5/16X72 ZN is designed to work with Eaton B-Line strut systems and can be installed using standard nuts and washers along with the SC3228 hanger rod stiffener for added rigidity. Pair it with channel nuts and compatible accessories from Eaton’s catalog for a secure, repeatable suspension. Confirm compatibility with your existing supports to ensure a clean fit.
The rated load capacity is 400 lb, suitable for medium‑duty suspensions such as electrical enclosures, light fixtures, and conduit runs. To ensure safety, distribute weight evenly and avoid concentrated loads. For dynamic conditions, including vibration or seismic considerations, refer to local codes and factor in potential moment loads when designing the hang points.
Key dimensions include an overall length of 72 inches, a diameter of 0.31 inches, an 18 inch thread length, and a weight of approximately 1.14 pounds per piece. These specs support straightforward integration with Eaton B-Line channel systems and standard fasteners, while allowing easy field adjustments for precise alignment during installation.
Zinc plating provides corrosion resistance suitable for indoor industrial environments and typical facility conditions. For outdoor exposure or highly corrosive environments, validate compatibility with your service conditions and consider additional coatings or enclosure strategies as part of a complete, code-compliant installation plan. Consult Eaton's guidance and your facility's maintenance team for specific protections.
Official Eaton datasheets and catalogs are available from Eaton’s website and the downloads section for ATR 5/16X72 ZN, including the B-Line series catalog sections and the specification sheet.
