Black - 3/8" 13 GA - Rope Pattern
Anodized Aluminum Open Jump Rings
Black 3/8 Inch ID (10mm) Jump Rings are large jump rings with a rope like pattern impressed on the side of the rings. This makes the wire slightly compressed side to side (not quite perfectly round) as well as having a half hard temper. These rings are made with 1.85mm thick wire (13 Gauge AWG) with an aspect ratio of 5.3. The aspect ratio should be considered approximate since the wire is not perfectly round. The outside diameter (OD) is 13.9mm.

Gauge - GA - AWG - this is the thickness of the wire. Most jump rings are manufactured using standard wire that is measured in gauges. We list our wire and jump rings using the AWG or american wire gauge system.
ID - inside diameter - measurement of the closed jump ring from inside edge to inside edge across the center.
OD - outside diameter - measurement of the closed jump ring from the outside edge to outside edge across the center.
AR - aspect ratio - specific to chainmail designs measures the inside diameter (ID) of the jump ring by the thickness (Gauge) of the wire or AR = ID / GA. This is a guideline measurement to determine whether a certain size jump ring will work with the weave you plan to use.
