UNC Double Swivel Ring - Codipro GradUP 3900lb is a purpose-built lifting ring designed for demanding rigging tasks where turning charges and misalignment are common challenges. Engineered for reliability, it combines precise movement with robust load handling, making it a staple for offshore, shipyard, and heavy industrial lifting operations.

• High-strength performance with a 5:1 safety factor and a working load limit (WLL) of 3,900 lb (1.76 t).
• Dual-axis movement under load—180° pivot under load and 360° swivel under load ensure controlled motion no matter the orientation.
• Certified traceability—manufactured inhouse in Luxembourg with full factory traceability. Includes Product Number DSR-U-058 and EN1677-1 compliance, plus a certificate of conformity and material analysis.
• Offshore-ready design—DNV-approved for offshore applications (Certificate TAS00001ZG), with data engravings detailing batch, material, and WLL to meet exacting standards.
• Turning-charge optimization—specifically engineered to handle skew or axial hoisting and stowing scenarios, reducing the risk of rotation-induced unloading and ensuring stable, predictable loads.
• Integrity through proper installation—tightening torque specified by the manufacturer; prefer rings whose axes remain inseparable from the equipment to maintain maximum effectiveness.
• Clear identification and safety emphasis—GradUP unique identification supports full service history, while engravings communicate EC references, class, batch details, diameter, and maximum CMU/WLL for quick on-site verification.

The UNC GradUP rigid ring is designed to excel where space is at a premium and loads are dynamic. Its compact form and threaded connection (5/8" UNC) paired with a solid base ensure a secure, reliable setup even under demanding offshore or heavy-lift conditions. Reducing complexity in lifting operations, this ring enables turning loads smoothly, aligning with hoisting gear, and simplifying stowage tasks without compromising safety.

Who benefits most: riggers, offshore technicians, shipyards, maintenance yards, and any operation requiring dependable turning and swiveling of heavy loads with traceable, certified parts.

Why this matters: unlike generic rings, the GradUP UNC double swivel ring emphasizes unique identification, full factory traceability, offshore certification, and explicit engineering controls—delivering real-world outcomes such as improved load stability, safer rigging cycles, and faster inspection routines. When you need a single, trusted solution for turning charges under load, this Codipro GradUP ring delivers clarity, compliance, and consistent performance strand after strand.
