<p>A "catseye" mounting has a base 2 of circular cross-section enabling it to be mounted readily and securely within a circular hole 9 formed in a road surface using a core-drilling machine. The machine can cut a larger upper recess 8 which receives a rim 3 of the mounting. A passageway 10 allows adhesive material to be injected into the narrow space between the mounting and the hole 9 and the tapered wall 12 of the base 2 results in a wedge 13 of adhesive material being formed which tends to hold the mounting securely in place. <IMAGE></p> |
