Abstract: A system for the protection of airport runway light fixtures and markers is disposed at or near the edge of aircraft runways, taxiway and airport signs. The system includes a thin flexible mat having an axial opening proportioned to enable placement above an elevated in-ground concrete base of a runway light fixture, and peripherally disposed apertures within the mat. The system further includes several anchors for the mat, each of which comprise a planar head, and means for penetration and engagement of earth upon which the mat is positioned. The penetration and engagement elements of each anchor integrally and rigidly depend from a lower surface of the planar head at a central axis. A greatest transverse cross-section of the engagement element is proportioned for complemental insertion within the peripheral apertures of the convex mat. The planar heads of the anchors each engage the mat when the engagement means have fully penetrated the earth upon which the mat is to be secured.
