What is a projecting light box (blade sign)?
A projecting light box, often referred to as a blade sign, is a double-sided illuminated commercial sign mounted perpendicular to the facade of a building. It utilizes a heavy-duty metal mounting bracket, allowing the circular or square acrylic faces to protrude over the sidewalk. This ensures maximum brand visibility for pedestrians walking up and down the street, rather than just those standing directly in front of the store.

How do you install a double-sided wall projecting light box?
Mark the Wall: Use the provided 1:1 fixing template to mark the exact locations for the mounting bracket holes on your building's exterior wall.
Drill and Route: Drill the structural mounting holes and one central hole to route the electrical power cable into the building interior.
Insert Anchors: Drive heavy-duty expansion bolts or wall anchors deep into the drilled holes to support the cantilevered weight of the sign.
Mount the Sign: Route the power cable through the wall, align the metal bracket of the light box with the anchors, and bolt it securely in place.
Power Connection: Connect the internal wiring to the provided Meanwell DC 12V transformer indoors, and plug it into the main AC power supply.
