Designed with unique identification and traceability, this ring nut keeps your rigging system compliant and auditable from manufacture to deployment.

Why it stands out

• Unique Identification & Traceability: Manufactured in-house in Luxembourg, EN1677-1 compliant, with a full factory traceability certificate included. Product No. FE.DSR-M20-UP.
• High Load Capacity & Safety: 2500 kg WLL with a robust 5:1 safety factor, providing a generous margin for critical lifts.
• 360° Swivel Under Load & 180° Pivot Under Load: The double swivel design allows the load to align naturally, reducing twist and wear on rigging lines while maintaining control under varying angles.
• Angle-Ready Load Ratings: Listed WLL at 0 and 90 degrees so you have predictable performance regardless of orientation.
• Durable, Ready-to-Use Construction: A purpose-built, single-unit ring nut designed for reliable daily use in industrial settings.

Who is this for?

Ideal for rigging professionals in construction, shipping, manufacturing, and warehousing who demand auditable, high-strength lifting hardware. Great for overhead cranes, winches, sling systems, and temporary lifting points where freedom of rotation at the attachment point matters.

Practical usage tips

• Ensure you’re using the correct M20 thread attachments and verify the WLL applies to your configuration and load angle.
• Inspect for cracks, deformation, corrosion, or any signs of wear before each lift; replace if integrity is compromised.
• Store in a dry, clean environment to preserve swivel performance and prevent seizing of joints.
