I recently noticed that my Zephyr arm appears to be missing a piece - a sort of plug that is inserted into each of the joints that keeps the pin in place. You can see the piece I'm talking about on the right side of the picture.
It looks like a part that is necessary to maintain the structural integrity of the arm, so I'm hesitant to use it again before repairing. So far calls and emails to Tiffen support have been unresponsive. Does anyone know what that piece is called and how I go about getting it repaired? Thanks!
