Tost release and chain links

I seem to remember a similar thread that mentioned minimum diameter of the Tost ring. Not the overall size, but the diameter of the metal that is captured by the release itself. The recommendation was to check the ring with calipers or a micrometer to make sure that the ring had not worn down to the point that it could be inadvertently pulled out of the mechanism. I have not been able to find reference to a minimum size. Anybody know the specification?

I seem to recall that back in the '80s Tost rings cost that much, if not
more.Â* A bargain by today's standards!

I also recall lots of folks using chain links on ground handling ropes
to move their gliders around on the airport.Â* This was before the wide
spread use of tow bars.Â* My partner and I used a Tost ring on our ground
handling rope.
