Captive bead ring with hinge.-

In regular captive bead rings (CBR) or ball closure rings (BCR), it is the ball that is removed and inserted to open and close the ring. However, this is not the case here. In this piece, the ball is part of the ring. The ball is attached to a hinged bar attached to the rest of the ring. This method allows you to open the ring easily with a simple click. And to close it, you only need to push the hinge back in - the end of the ring will snap into a small recess. 

The ring is available in several different colors that you can see in the pictures. The ring, regardless of the color choice, has a diameter of 5/16" (8 mm), a gauge size or thickness of 16g (1.2 mm), and a ball of 3 mm.
