This is a pair of OBD Slimline Stainless Bridle Inserts for making loop band, roller or invert speargun rubbers.

Specially reduced ball size to provide easier fitment to small bore rubbers, whilst also minimising expansion and perishing of any bore size rubber.

Made from quality strong stainless steel, they have a 6.25mm diameter round ball for inserting and are 25mm long in total.

The attachment hole will accomodate lines up to 2.1mm in diameter.
