Gap Measurements Cobra

On this page, you can find the gap measurement for each combination of Cobra cage, ring size, and ring style. For general information about ring sizes, check out our base ring size guide.

All gap measurements are rounded to the nearest millimeter.

Note: These measurements reflect the position where the two cage pins are fully pressed into the base ring slots. The true gap of your device may increase slightly if the cage pins are not fully pressed into the slots, or if you are using the O-rings that are included with KINK3D cages.
