Crosby HG-226 Eye & Eye Turnbuckle � Heavy Duty Galvanised Rigging Turnbuckle

Description

The Crosby HG-226 Eye & Eye Turnbuckle is a premium-quality rigging component designed to provide precise tension control in wire rope, cable, and structural support systems. Built to withstand demanding industrial environments, this turnbuckle is widely used in construction, marine rigging, structural bracing, and heavy-duty cable tensioning applications.

Manufactured from high-strength steel components, the HG-226 turnbuckle features quenched and tempered or normalised end fittings, while the central body is heat-treated through normalising to ensure consistent strength and mechanical reliability. This advanced manufacturing process provides enhanced durability and resistance to fatigue, making the turnbuckle suitable for repeated tensioning operations and heavy load conditions.

To maximise corrosion resistance, the entire assembly is finished with hot-dip galvanisation, providing excellent protection against moisture, salt exposure, and harsh environmental conditions. This protective coating makes the HG-226 particularly suitable for outdoor installations, marine environments, infrastructure projects, and industrial sites where corrosion resistance is essential.

The forged eye end fittings are specifically engineered with an elongated design, allowing easier connection within rigging systems while reducing stress concentrations in the eye during loading. This thoughtful design improves load distribution and enhances the overall fatigue life of the component. For turnbuckles ranging from 1/4 inch through 2-1/2 inch sizes, a shackle one size smaller can be reeved through the eye, simplifying rigging installation and increasing compatibility with common lifting hardware.

The HG-226 turnbuckle also incorporates modified UNJ threads on the end fittings, which significantly improve fatigue resistance compared to conventional thread forms. The turnbuckle body features UNC threads, enabling smooth adjustment and reliable tension control when aligning or tightening rigging assemblies.

Designed for long-term operational reliability, the HG-226 is fatigue rated to 20,000 cycles at 1.5 times the Working Load Limit, demonstrating its capability to perform consistently under repeated loading conditions. The turnbuckle also features a 5:1 design factor, with a proof load tested at 2.5 times the Working Load Limit, providing a strong safety margin for demanding rigging operations.

Crosby manufactures the HG-226 to meet or exceed ASME B30.26 requirements, ensuring compliance with critical standards related to identification, ductility, proof load testing, design factor, and temperature performance. Beyond these requirements, Crosby engineering standards also address fatigue performance, impact resistance, and full material traceability, delivering enhanced reliability for professional rigging applications.

Additionally, the HG-226 meets the performance requirements of Federal Specification FF-T-791b Type 1 Form 1 Class 4 and ASTM F-1145, ensuring suitability for a wide range of industrial and structural applications.

The eye & eye configuration provides a secure and permanent connection point for shackles, hooks, or other rigging hardware, making it ideal for structural tensioning and fixed rigging installations. Optional lock nuts are available for all sizes, allowing users to secure the desired tension setting once adjustment is complete.

It is important to note that turnbuckles should only be used for straight or in-line pulling applications, ensuring loads remain properly aligned and preventing side loading that could reduce product performance or safety.

With its forged eye design, galvanised corrosion protection, fatigue-resistant thread system, and Crosby-engineered quality, the HG-226 Eye & Eye Turnbuckle provides a dependable solution for professional rigging, cable tensioning, and structural load control systems.

Safety & User Instructions
Turnbuckles are recommended for straight or in-line pulling applications only.
Ensure eyes are properly aligned with the load direction before tensioning.
Inspect threads, eyes, and body for damage, corrosion, or deformation before use.
Maintain sufficient thread engagement within the body during adjustment.
Do not exceed the specified Working Load Limit.
Use lock nuts where necessary to prevent loosening under vibration.
Follow ASME B30.26 rigging safety guidelines during installation and operation.
