A channel letter has a rear surface for mounting against a raceway, wall, or a structure for supporting the signage, and sheet metal sides defining the figuration of the letter of shape to be depicted. A lighting element is positioned against the rear surface of the enclosure, and a lens is retained to the open front of the enclosure. The lens is retained by a plurality of retainer clips to a shoulder recessed within the walls of the enclosure and a cable between opposing walls provides lateral support to the walls. Each of the retainer clips has a first and a second leg extending from a back with the legs spaced a distance sufficient for the legs to fit around the end of the sheet metal of the walls. A partially flexible finger extends from one of the legs into the space between the legs so a to wedge against a surface of the sheet metal wall and thereby retain the retainer clip to the wall.
