A. Description. Blade Signs: This sign type is mounted perpendicular to a building’s facade. Blade signs are typically hung from decorative cast or wrought iron brackets in a manner that permits them to swing slightly. These signs are small, pedestrian-scaled, and easily read from both sides. Often, a projecting sign offers the opportunity for a more creative or “playful” sign. Blade signs should be hung well out of reach of pedestrians and all exposed edges of the sign should be finished.
