D Ring Types

ATTMachine offers a range of D Ring types for cargo tie-down and load-securing applications, including weld-on, bolt-on, recessed and heavy-duty designs. Select the appropriate D Ring based on the required load rating, mounting method, material and application.

Weld-On D Rings

Weld-On D Rings are permanently secured to compatible steel structures by welding, providing a robust anchoring point for cargo restraint systems. They are commonly used on trailers, trucks, flatbeds, equipment frames and other heavy-duty applications. Welding procedures and the supporting structure should be appropriate for the required load and application.

Bolt-On D Rings

Bolt-On D Rings are mechanically fastened to a suitable mounting surface using bolts or other compatible hardware. This configuration allows straightforward installation, inspection and replacement, making it suitable for applications where a removable or serviceable anchor point is preferred.

Recessed D Rings

Recessed D Rings are installed into a recessed mounting pan, allowing the ring to sit closer to the surface when folded down. This low-profile design helps reduce interference with cargo and provides a cleaner loading surface, making it widely used on trailers, trucks and vehicle cargo floors.

Heavy-Duty D Rings

Heavy-Duty D Rings are engineered for demanding cargo tie-down and load-securing applications that require a strong and durable anchoring point. Available load ratings depend on factors such as ring dimensions, material, construction, mounting method and overall system configuration.

Custom D Rings

ATTMachine provides custom D Ring manufacturing for OEM and industrial applications based on technical drawings, samples, specifications or required dimensions. Custom options can be developed to meet specific requirements for material, size, finish, mounting configuration and production volume.

D Ring Specifications

D Ring specifications are confirmed according to the individual product model.

MBS & WLL

For load-rated D Rings, Minimum Breaking Strength (MBS) and Working Load Limit (WLL) should be specified for the individual product model.

International cargo-control manufacturers commonly publish MBS/WLL together with ring size, material and mounting configuration rather than applying one load rating to an entire D Ring category.

ATTMachine does not recommend selecting a D Ring based on a generic category rating. Always use the product-specific specification and consider the complete mounting system.
