Our goal is to provide sign manufacturers and wholesalers with the most efficient, time and money saving aluminum extrusion for their channel letter jobs. The 2-piece channel letter raceway extrusion system allows for a quick mount with minimal work. The back is mounted to the wall independent of the face. Once the back is in place, the front (with letters already mounted) is easily set on the back piece. Once end caps are fastened, the raceway is completely enclosed and the job finished. NO fabrication required.
