This Dual Lit wall mount sign illuminates through both its acrylic face and clear polycarbonate (Lexan) back, creating a halo effect. The letters are spaced 12 inches from an aluminum backer (full size raceway), which is securely attached to the building wall. To streamline installation, the letters are preassembled onto the backer in the shop as a single unit, saving valuable time during field installation. The backer, or full size raceway is a practical choice, minimizing wall penetrations and neatly housing power supplies and wiring. This setup is particularly ideal when there is no electrical access behind the wall, requiring only a single electrical whip to power the entire assembly.
