The Round Rod Extension extends helical anchor lead sections to the required depth in soil applications with weak conditions requiring moderate holding capacity. It connects to guy adapters and multi-helix anchors through square shaft ends on its round rod body. A high-strength bolt and nut are factory-assembled to the extension, with a drilled hole in the shank engaging the guy adapter bolt.
Constructed from steel with a hot dip galvanized finish conforming to American Society for Testing and Materials (ASTM) Specification A123, the extension provides corrosion protection. The forged construction delivers a tensile strength of 70,000 pounds and a torque rating of 2,300 foot-pounds.
Standard dimensions include a 1.25-inch diameter with lengths from 3.5 feet to 10 feet. Weight varies by model, approximately 28.42 pounds for a 5-foot length. Installation requires alignment within 5 degrees of the guy load direction to maintain rated strength. The product arrives factory-assembled and ready for immediate installation.

Frequently Asked Questions（FAQS）
How does the round rod extension ensure durability and compliance for critical infrastructure projects?
The round rod extension is designed with a tensile strength of 70,000 lb and a torque rating of 2,300 ft-lbs, providing robust performance for demanding applications. It is hot-dip galvanized per ASTM A123 for superior corrosion resistance and forged from high-strength steel for long-term reliability in harsh environments commonly encountered in utility and infrastructure projects. These specifications are validated for properly installed anchors, with alignment within 5° of the guy load critical to achieving advertised performance.
What lengths are available for the Round Rod Extension?
Extensions are offered in lengths ranging from 3.5 feet to 10 feet, allowing for flexibility in installation depth and adaptability to different project requirements, from small-scale repairs to large-scale grid expansions.
How is the round rod extension designed to facilitate quick and secure installation?
Each extension comes with a high-strength bolt and nut assembled at the factory, ensuring components are pre-fitted for ease of use. This design reduces installation time and minimizes the risk of errors. The extension is used to install the anchor lead section to the proper depth and should be installed within 5° of alignment with the guy load for optimal strength. The lead section and guy adapter are sold separately.
Are there any installation precautions for the Round Rod Extension?
Yes, ultimate strength ratings apply to properly installed anchors only. Failure to install within 5° of alignment with the guy load may significantly lower strength.
