This bead keeper is machined from solid titanium. The post is just under 1/4" in diameter and it has a 1.25" space between the split ring and shoulder.

I'm not sure what happened to this bar of titanium but there is a crack down one side and a little chunk missing on the post. Its still strong a hell, the bar survived the machining process, think of it as coming with battle damage.

It comes with a 11mm stainless split ring.
