A small double loop for attaching the karabiner the the rig.
Wraps around the brushbow and the karabiner fits through the loops.
Softer attachment than metal to metal of karabiner/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.
The price is the same for each.
