This UNIQUE SEW D-ring shackle is a bag-making connector used to attach straps, handles, and hardware on sewn accessories like totes and backpacks. It is sized for 25 mm (1 in) webbing or straps and comes as a 2-piece pack in a silver finish for coordinating with other metal findings. Match it to your strap width before installing, and keep hardware dry and clean to help reduce surface wear over time.
