Front lit, or standard, channel letters have an aluminum back, aluminum sides (called returns) and acrylic faces. We start by using a router to cut a flat sheet of aluminum into the shape of the specified letter or number. The returns are then formed by bending a strip of aluminum around the back and fastening it to the back, forming a can. The can is custom painted to the specified color and fitted with a light fixture (usually LED). The acrylic face in the desired color is cut to fit the can and is attached with a trim cap to finish the process. Front lit channel letters are highly visible during the day or night and are the most popular type of channel letter.
Channels letters may be flush mounted directly onto the building or mounted on a raceway. A raceway is a metal box that contains the channel letters and the wiring and power supply for the lighting. It can be painted to your specified color. Raceway mounted signs require fewer building penetrations. Standard channel letters may also be mounted on a top and bottom rail which are attached to the building.
