This Halo Lit / Wall Mount Free Standing on Ledge Raceway sign type allows light to shine brightly through its rear, clear polycarbonate (Lexan) back and is mounted on top of a ledge raceway with round or square tube stand-offs. The raceway is then installed flush to the building's wall surface becoming the only source of attachment minimizing penetrations to the wall. The free-standing letters are set 1"-2" from the back of the raceway and wall surface for an elegant halo effect.
