Wholesale Double-Sided Logo Boxes Double-Sided Logo Boxes
Dual-face logo cabinets that capture attention from both directions of traffic. Engineered for pole, pylon, and monument installations.
When Single-Face Visibility Isn't Enough
Not every sign installation has the luxury of facing a single direction of traffic. Pole-mounted signs along roadways, double-sided blade signs, monument signs at property entrances, and median-positioned pylons all serve traffic approaching from opposite directions. A single-face logo box in these applications wastes half its potential audience — drivers coming from the opposite direction see nothing but a blank aluminum back panel. Double-sided logo boxes eliminate this limitation by presenting the brand identity on both faces simultaneously.
Double-sided logo boxes are structurally different from their single-face counterparts. The cabinet requires two face panel openings, internal LED illumination that serves both sides without cross-contamination, and a structural internal framework that maintains rigidity across a wider cabinet depth. The mounting system must also account for significantly higher wind loads, since the double-face configuration acts as a larger sail area than a single-face unit of the same dimensions.
At Sunlite Signs, we engineer double-sided logo boxes as purpose-built assemblies — not two single-face cabinets bolted back to back. Our approach uses a single welded aluminum cabinet with internal divider that creates two independent illumination chambers. This construction method is lighter, stronger, and thinner than the bolted-together alternative, and it produces cleaner sight lines from the edge profile view. Every double-sided unit is UL 48 listed and ships ready for your crew to mount and wire.
Internal Engineering for Dual-Face Illumination
The engineering challenge unique to double-sided logo boxes is managing illumination for two faces within a single cabinet — our electrical engineering optimizes each chamber. If LED modules are mounted on a flat center divider, each face receives its own dedicated light chamber — this is the simplest approach and the one we use most frequently. However, some designs require more sophisticated solutions:
- Center Divider System: A solid aluminum panel bisects the cabinet, creating two sealed chambers. LEDs mount on each side of the divider, facing their respective face panels. This is the standard configuration for cabinets 6" deep or greater, providing ample LED-to-face distance for uniform illumination
- Shared Module Configuration: For thin-profile cabinets under 6" deep, we use dual-emission LED modules that project light in both directions from a single strip. This eliminates the center divider, reducing cabinet depth while still achieving acceptable face illumination
- Independent Circuit Control: Each face can be wired to a separate driver circuit, allowing one side to be dimmed or turned off independently. This is useful for signs near residential areas where one face is visible from homes and may need nighttime dimming to comply with light pollution ordinances
We calculate LED layout for each face independently because the two sides may have different graphics — a common scenario when one face displays the brand logo and the other displays address information or a secondary brand mark. Different graphic densities and color distributions can require different LED spacing to achieve consistent brightness across both faces.
All power supplies are mounted in accessible compartments — typically at the bottom of the cabinet or in an external junction box on the mounting pole. Our wiring layout ensures that a technician can service one face's LED array without disturbing the other side's system.
Mounting Systems for Poles, Pylons & Monuments
Double-sided logo boxes are most commonly installed on pole mounts, pylon structures, and monument sign bases. Each mounting scenario has distinct structural and aesthetic requirements that Sunlite Signs addresses during the engineering phase:
- Direct Pole Mount: The logo box attaches to a round or square steel pole using a welded internal bracket system. We engineer the bracket to accept standard pole diameters from 4" to 12" and distribute the sign's wind load evenly into the pole structure. The pole penetration is concealed inside the cabinet for a clean appearance
- Pylon Cabinet Integration: Double-sided logo boxes frequently serve as the tenant ID panels within a multi-tenant pylon structure. We fabricate the logo box to fit the pylon's internal track or bolt pattern, with dimensional tolerances that ensure a flush fit with the pylon's uprights and crossbars
- Monument Base Mount: For ground-level monument signs, the double-sided logo box sits atop a masonry, stone, or aluminum base structure. We provide a bottom-mount cleat system that secures the cabinet to the base and routes electrical conduit through the base interior into the sign cabinet
Wind load engineering is particularly critical for double-sided installations because these signs typically stand on elevated poles or exposed structures where wind forces are highest. Our structural calculations account for the full effective wind area of both faces, applying the appropriate ASCE 7 coefficients for double-face sign configurations. We provide PE-stamped engineering drawings when required for permitting, covering the sign cabinet, mounting hardware, and connection to the support structure.
