Titanium Bar Closure Ring. This is similar to a Ball Closure Ring (BCR) but instead of the ball, a short, straight bar (with small recesses at either end) is held in place by the tension of the ring. This makes a good alternative to a BCR. Another ring to consider is the Segment Ring (which is similar to the bar closure ring except the insert is curved giving the illusion of a full unbroken circle).
Suitable for Autoclave.
