A small double loop for attaching the karabiner the the rig.
Wraps around the brushbow ( or bike / scooter stem ) and the karabiner fits through the loops.
Softer attachment than metal to metal as in karabiner direct to rig.
Eliminates the ‘clanking’ of karabiner on the rig, scooter or bike when running, and saves paintwork!.
Note that the smaller and lighter double loop is for 1-3 dogs ganglines, scootering or bike-joring, while the heavier one, denoted by the black fleck running through, is for 4 dogs and up.
