When your project demands precise tension adjustment, robust load management, and uncompromised safety, the US Type Wire Rope Turnbuckle with Jaw & Jaw configuration stands as the industry benchmark. Designed to meet exacting US Federal Specifications, this hardware is the preferred choice for marine rigging, heavy construction, and critical infrastructure across European and American markets .
Our US Type Turnbuckle distinguishes itself through a combination of advanced metallurgy and precision engineering. Unlike standard turnbuckles, this unit features drop-forged, heat-treated carbon steel construction with quenched and tempered end fittings, delivering superior strength compared to cast alternatives . The result is a durable tensioning solution capable of withstanding the severe demands of dynamic loading in offshore, industrial, and architectural applications .
Key Features & Advantages
Jaw & Jaw Configuration: Designed for rapid attachment and secure release, the jaw ends utilize a nut, bolt, and cotter pin assembly. This provides a safer, more secure connection than hook ends and offers greater flexibility than fixed eyelets, making it ideal for straight-line tensioning of wire ropes and aircraft cables .
Hot-Dip Galvanized Finish: Engineered to endure the harshest environments, the hot-dip galvanizing offers exceptional weather and corrosion resistance. This ensures long-term durability and minimal maintenance, even in high-humidity marine or outdoor settings .
High Safety Factor: Every unit is proof-tested to 2.5 times the Working Load Limit (WLL) with a minimum breaking force of 5 times the WLL, ensuring a significant margin of safety for critical operations .
Precision Threading: Featuring UNC threads with right-hand and left-hand combinations, the turnbuckle allows for simultaneous adjustment of both ends without twisting the attached cables or end fittings, simplifying installation and tensioning
