Placement.
Figure 3‑18 shows the placement for Guide Sign Routing plaques.
Plaques should be horizontally centered at the top of the parent guide sign.
If the parent guide sign includes an Exit Number panel, the plaque (or plaques) should be centered between the Exit Number panel and the opposite sign edge. A spacing of 6 inches between the edge of the sign and the Exit Number panel is desired.
If there is not enough space to place a routing plaque in between the Exit Number panel and the sign edge, the plaque may be placed above the Exit Number panel.
