Metal D Ring Buckle

Connection Point for Straps, Handles, and Hooks

The Metal D Ring Buckle is a connecting component commonly used between shoulder straps, handles, hooks, and webbing. It is suitable for handbags, backpacks, crossbody bags, camera bags, sports bags, pet leashes, and outdoor equipment.

The D-shaped structure places the main connection area along the straight side. This makes it easier to attach a leather loop, insert webbing, or connect a snap hook. It can also help reduce side-to-side movement of webbing during use.

Available materials include zinc alloy, iron, stainless steel, and brass. The material and surface treatment can be selected according to the intended load, product positioning, and color scheme of the other hardware.

Dimensions, Structures, and Reference Performance

The internal width ranges from 10 mm to 50 mm. Wire diameter or frame thickness ranges from 2 mm to 8 mm.

Available structures include welded closed rings, seamless rings, one-piece die-cast rings, and open rings.

The reference static tensile load is 200–1,200 N. The reference salt spray time is 24–96 hours.

For shoulder straps, handles, or other primary load-bearing positions, a welded closed or one-piece die-cast structure is generally more suitable for evaluation. An open ring is more appropriate for decorative or light-load positions and should not replace a connection component that has been tested for the required load.

Actual performance depends on the material, structure, frame thickness, installation method, and complete assembled product. The stated load and salt spray ranges should therefore be confirmed for the final specification.

The surface can be polished or tumbled to create smoother contact areas. This helps reduce wear where the straight and curved parts of the ring touch leather, fabric, or webbing.

Zhejiang Tongtai Lock Industry can adjust the internal width, frame thickness, and connection structure according to the webbing width, leather-loop dimensions, snap-hook opening, or installation position.

Buyers may provide a technical drawing or physical sample for product copying, dimensional modification, or new product development.

Before volume production, a sample can be used to check the clearance between the Metal D Ring Buckle, shoulder strap, snap hook, and leather loop. This is particularly important when several hardware components must move together without excessive looseness or interference.

The factory checks the ring dimensions, straight-side length, opening condition, welding position, and surface smoothness.

Externally finished products are inspected for appearance after returning to the factory. Process inspections are performed during production, and every finished product is checked before packaging.

Regular models have no fixed minimum order quantity requirement. Custom packaging normally requires 1,000–2,000 pieces. Different colors or models may be mixed in one order, although a larger number of colors must be coordinated with the surface-treatment schedule.

Buyers may appoint a third-party inspection company to inspect the products at the factory. For products used under continuous load, the target tensile requirement and salt spray time should be confirmed during quotation and sampling.

After delivery, the sales team can assist with application review, installation suggestions, and eligible replacement matters.
