Product review (1 stars): Find the old style all plastic part.
Complete junk. Will break before most other parts as designed, this is the weak point in system. The metal collar will then be stuck, which will be very difficult to remove. Possibly causing breakage further up the line as well. Making a ten minute fix turn into a gaint ordeal or buying of more parts. The old style all plastic part is what you should fix this with, it will break and not become locked up. Good luck finding them though.
