1. A replaceable, wet-set tactile warning surface unit, comprising:
- a body defining an upper surface and a lower surface, the body defining a series of raised projections on its upper surface, and defining a plurality of spaced through-holes from the upper to the bottom surface, in which the raised projections are spaced from one another and the through-holes are located between projections; and
an equal plurality of anchor members coupled to the bottom surface of the unit member directly below the through-holes by an equal plurality of fasteners that pass through the through-holes.

Abstract
A replaceable, wet-set tactile warning surface unit having a body defining an upper surface and a lower surface, the body defining a series of raised projections on its upper surface, and defining a plurality of spaced through-holes from the top to the bottom surface, in which the raised projections are spaced from one another and the through-holes are located between projections. An anchor member such as a threaded insert is coupled to the bottom surface of the unit member directly below each of the through-holes by fasteners such as bolts that pass through the through-holes.

12. A method of installing a replaceable, wet-set tactile warning surface unit, said unit having an upper surface and a lower surface, the body defining a series of raised projections on its upper surface and defining a plurality of spaced through-holes from the upper to the lower surface, comprising:
-
installing a plurality of fasteners through the plurality of through-holes; affixing an anchor member to each of the plurality of fasteners, such that the anchor members are proximate the lower surface of the body; and placing the unit into fresh concrete and applying force to the top of the unit to embed the unit in the concrete such that the unit edges are approximately flush with the top surface of the concrete. - View Dependent Claims (13, 14)

19. A replaceable, wet-set tactile warning surface unit comprising:
-
a body defining an upper surface and a lower surface, the body defining a series of raised projections on its upper surface, and defining a plurality of spaced through-holes from the upper to the bottom surface, in which the raised projections are spaced from one another; and a perimeter flange that is thicker than the rest of the body comprising a plurality of spaced slots passing through the perimeter flange that allow air to escape from underneath the unit when it is installed in fresh concrete, wherein the plurality of through-holes is configured to accommodate an equal plurality of fasteners that pass through the through-holes, such that an equal plurality of anchor members may be coupled to the bottom surface of the unit member directly below the through-holes by the equal plurality of fasteners. - View Dependent Claims (20)
