a second surface on the second bracket, and the second surface is spaced apart from the second plate; and
the first wedge part is wedged against the second surface.
17. The tactile embedment plate assembly of claim 11 , wherein:
the first wedge part is formed integrally with the first bracket.
18. The tactile embedment plate assembly of claim 11 , wherein the second wedge part is formed integrally with the second bracket.
19. The tactile embedment plate assembly of claim 11 , wherein:
the first bracket shoulder includes a lip for engaging a notch in a lower surface second plate.
20. The tactile embedment plate assembly of claim 11 , and further comprising:
a lip on the second bracket for engaging a notch on the first embedment plate.
21. An alignment bracket for aligning a first tactile embedment plate to a second tactile embedment plate in a substantially co-planar relationship, the alignment bracket comprising:
a first bracket joined to the first tactile embedment plate;
a second bracket joined to the second tactile embedment plate and aligned with the first bracket; and
a clip releasably joined to the first bracket and the second bracket.
22. The alignment bracket of claim 21 , wherein the first bracket comprises:
a shoulder on which the second tactile embedment plate bears.
23. The alignment bracket of claim 21 , wherein the first bracket comprises:
