Double-Sided Light Boxes That Catch People Coming From Both Directions
A flat sign on the wall is easy to miss when people walk or drive along your street. They see it edge-on. A double-sided light box, or projecting cabinet sign, sticks out from the building, so it faces the traffic itself.
Two lit faces mean your name is in front of people approaching from either side, day and night.

What a Double-Sided Light Box Is
It is a cabinet with two translucent faces, one on each side, mounted at a right angle to the wall on brackets that hold it a short distance off the facade. LED lighting inside lights both faces evenly. Most projecting light boxes are round; some are square.
Projecting signs are common on main streets and narrow frontages where the business name would otherwise be visible only to people already standing in front of the door. By day both faces show your printed graphics; at night they glow, turning the sign into a landmark along the block.
Why a Projecting Sign Works
Seen from both directions
Two faces put your name in front of pedestrians and drivers coming either way.
Visible down the street
Because it faces the traffic, a projecting sign can be read before people reach your door.
Ideal for narrow frontages
When your storefront is small, a projecting sign gives you presence along the whole block.
Lit edge to edge
LED modules with optical lenses light both faces evenly, without dark spots.
Same graphics, double the exposure
Both faces are UV-printed with your graphics, so the sign works for every passer-by.
When to Choose Double-Sided, and What to Check First
- Your business is on a street with foot traffic or slow-moving cars
- The storefront is narrow or set back, and a flat sign would be seen edge-on
- There is room on the wall for a bracket and safe clearance below
The City of Calgary states that “all new canopy and projecting signs require a development permit,” and that businesses “can have only one projecting sign on a primary building wall” (calgary.ca, checked 2026-10-28). We handle all the sign permit paperwork: we prepare the drawings, specifications and documents and submit the application on your behalf. If you prefer to apply yourself, you get the complete package from us, ready to submit.
If the sign will be read mainly from the front, a flat single-sided light box is simpler and usually more economical.
How It Is Built
Two faces, one cabinet
Both faces are printed and lit from the same cabinet, so they match in brightness and colour.
Round or square
The shape follows your logo. A round cabinet suits a logo built around a circle, a square one suits a compact logo or a short name. Usually both faces carry the same printed design.
Bracket and mounting
The brackets hold the cabinet off the wall and are planned for the wall material and the size and weight of the sign, so it stays secure through wind and snow.
Lighting
LED modules rated for up to 50,000 hours with optical lenses, arranged for even light on both faces.
Bench-tested
The finished sign is lit and checked in our workshop before installation.
What Affects the Price
A double-sided cabinet has two printed faces and a projecting mount, so it is calculated for each project. Installation is quoted separately (about CAD $100 per hour plus GST as a guide). Already have a projecting box? A face replacement may be enough.
