The Clip In Ball is neatly clipped between the closure ring with a ball closure tool. Please double check the ball size, as it has to fit precisely between the closure ring ends. This item is also available in the Titan Highline® (TLB), the Titan Blackline® (KLB) and in the Titan Zirconline® (GCB). In the Titan Highline®, it is available anodised, also. There is a replacement ring to complete your BCR in the Steel Basicline® (CBCR/CIMP). The item can, like all basics, be sterilised in an autoclave and is hypoallergenic. If you have any questions, please do not hesitate to contact us for advice!
