Abstract: A channel lighting sign is provided in which the side structure of the channel lighting sign can be constructed of a translucent polycarbonate material. The channel lighting sign includes a faceplate foamed of a translucent or transparent material, such as an acrylic plastic. The side structure is shaped to conform to perimeter contours of the shape of the faceplate. At least one mounting bracket is disposed on an inside surface of the side structure at a position near a front side of the side structure. The mounting bracket holds a mounting insert formed of a material that can easily and quickly bond with the faceplate material using a solvent or bonding agent.
