Abstract: An exhaust treatment device includes a dosing and mixing assembly having a wire mesh puck. A retaining arrangement holds the mesh puck and maintains the mesh puck in an axially compressed state. The compressive force may be sufficient to inhibit rotation of the wire mesh. A peripheral side of the wire mesh is allowed to float while edges of the axial ends are trapped between at least two stop members of the retaining arrangement.
