Cabinet Design Options: Flat, Routed & Push-Through Faces

One of the biggest advantages of LED light box signs and cabinet signs is their flexibility in construction and appearance. Depending on your branding goals and desired visual impact, illuminated cabinet signs can be fabricated with different face styles:
  • Flat Face Cabinets – A clean, smooth acrylic panel with applied graphics, ideal for simple, cost-effective branding with even illumination.
  • Routed Face Cabinets – Metal faces that are precision-cut (routed) to reveal illuminated areas for logos or text, offering a more custom, dimensional look.
  • Push-Through Acrylic Letters – Acrylic elements that extend through a routed metal face, creating depth and a high-end, dimensional appearance with enhanced lighting effects.
These options allow businesses to choose between a more economical flat-panel solution or a more architectural, dimensional sign that adds visual interest to the space.
