Ring Buckles – D-Rings, Flat D-Rings and Round Rings

Ring buckles – the connecting link of the strap

Ring buckles have no prong and no moving parts – they are a closed or almost closed metal frame through which the webbing passes. That makes them extremely reliable: they attach the shoulder strap to the bag, act as an attachment point for a snap hook, join two straps or close a double-ring belt. In this category Polkom, a manufacturer of metal accessories, offers D-shaped, flat D and round rings wholesale in sizes from 10 to 50 mm. For the full range of rings in other shapes, see also the Rings section.

Models in the catalogue

D-shaped wire ring (KT-07)

The most common shape. The straight side takes the webbing evenly, while the rounded side remains free for a snap hook, a hook or a second strap. Used on bags, backpacks, belts and gear.

Flat zinc alloy D-ring (KT-08)

A cast model with a flat, low profile. It looks more solid and more elegant than a wire ring and suits thin straps and minimalist fashion accessories.

Round ring – O-ring (KT-09)

The round shape gives a soft, seamless look and free movement in all directions. Suitable for decorative straps, double-ring belts and joining several tapes at one point.

How to choose a ring

• The inner width of the straight side should match the width of the webbing.
• For heavy bags and gear, choose thicker wire or a cast model.
• Round rings are suitable when the webbing needs to move freely.
• The flat D-ring is the better choice when the ring is visible and part of the design.

Finishes

The rings are available in finishes from our colour card – nickel, antique brass, black nickel, gold, gunmetal and others. Choose the same finish as the product's metal buckles and eyelets so that the metal accessories look like one set. The wire and cast rings in this series are not made with a logo.

Fitting and use

The ring is attached by sewing: the webbing is passed through it, folded and stitched. With wire models, make sure that the point where the wire ends meet is not under the greatest load. For bag shoulder straps and dog collars, we recommend testing a sample under real load before series production.

Welded, cast or wire ring

Wire rings are bent from wire and their ends meet at one point. They are light, economical and entirely sufficient for most bags, garments and accessories. A cast ring is a single solid piece without a joint, so it is suitable when the ring is visible and must look solid, or when the load is higher. When choosing, consider not only the width but also the thickness of the material – thicker wire takes more weight but also requires a wider fold of the webbing.
