Description
A 20 mm D-ring in zinc alloy for anchoring a strap, a handle or a clip to a bag panel. The flat bar sits inside the seam and the round side takes the load — on this part the shape and the wire diameter matter more than the finish.
Inside Width, Not Outside Width
D-rings are quoted on inside width: 20 mm here, matched to 20 mm webbing. Outside width is roughly the inside width plus twice the wire diameter, so a ring sold as “20 mm” measured on the outside will not take a 20 mm strap. Send the strap width and we will confirm the ring that actually fits instead of shipping to a nominal size.
How the Ring Is Made Decides How It Fails
Cast, not welded. A cast D-ring has no joint. A welded ring is cheaper, but the weld is the weak point, and on a shoulder bag that weld carries the full weight of the contents every time the bag is lifted. Ours are cast in one piece.
Wire diameter against load. Thicker wire resists opening, but it eats into the inside width. We size the wire to the load you specify rather than to one stock gauge, so a 20 mm ring can be supplied at more than one strength.
Seam clearance. The flat bar is what gets stitched into the panel. Too thick and it puckers the seam on lightweight leather; too thin and it pulls through under load.

Pairs With
Shoulder bag and tote strap anchors, detachable handles, and the 20 mm snap hook used as the detachable end of the same strap.
Send your strap width and the weight the bag is rated to carry, and we will come back with the wire diameter and unit price.
