§ 21.15.2723. Sign, push-through.
Latest version.
"Push-through sign" or "push-through cabinet sign" refers to a cabinet sign with sign copy rendered in relief either in front of or behind the sign face, similar to channel letters. A push-through sign typically is internally illuminated with an opaque face, creating a halo effect, although other designs such as illuminated letters or exposed neon in open-faced letters are acceptable as well.
