Mesh is positioned at both ends of the spacer. First and second retainers are receivable at the ends of the spacer adjacent to the mesh positioned thereat and have openings therethrough in correspondence with the spacer passageway. The mesh is thus held apart a selected distance with the passageway through the spacer enshrouded by the mesh yet accessible at both ends through the mesh and the openings in the retainers.
