A classic powerlifting competition collar. You would never have a use for these if you don't compete in powerlifting though. They are pretty expensive as far as collars go, but they do weigh 2.5KG and they really are specific to competition. My one gripe on these is the secondary tightening method has a tendency to get locked up on these and its really hard to get that loose once it's locked up. It's probably mostly user error from gym members doing dumb things with these.
