The D Rings is a heavy-duty weld-on lashing fitting widely used in container transport, truck chassis, construction machinery, and industrial platforms. With a robust forged structure, it is designed to be welded directly onto steel surfaces and works in conjunction with chains, slings, or wire ropes for securing, lifting, or towing cargo.

At OLIPORTS, our turnfoot D-Ring products are made from forged high-strength alloy steel, heat-treated and shot-blasted for superior mechanical performance and corrosion resistance. These lashing points are built to perform in the toughest working environments.

To accommodate different load requirements, we offer two distinct capacities:

• 50 Ton D Ring — Designed for ultra-heavy-duty applications
• 36 Ton D Ring — Ideal for general-purpose medium-to-heavy load securing

Whether for military-grade transport or industrial logistics, the OLIPORTS D Ring series delivers durable, efficient, and standards-compliant securing solutions you can rely on.

Compact, durable, and fully ISO-compliant, this fitting is essential for standardized container lashing and securing systems on modern vessels.
