The way our panniers attach to a rear rack is very simple, but effective. We designed these panniers for commuting and shopping in mind. So we wanted them to be very quick and simple to take on and off, without sacrificing stability on the rack.
On the underside of the center panel of the bags are two velcro straps that hook underneath the top plate of the rack:
For this system, we use a rubberized hook that latches to the bottom stay of a standard rack made to hold panniers (some racks are not made for this, and don't have a horizontal stay or curve at the bottom.)There is a webbing guidance system on the backs of the bags to help keep the hook and cord in position.
On the top center panel of the bags is the adjustment point for the cord. It runs up through metal eyelets and cinches down at the top:
