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.
