The body of Delta Street Light series is made of aluminum with an anti-corrosive coating to protect it in caustic environments, such as salt spray. The acrylic optical cover has a high-impact resistance, and the luminaire is sealed with resilient gasketing to prevent ingress. Available options include a 2-3/8" adjustable pole mount, as well as slip-fitters in order to adapt to other mounting requirements. Pole arms are not included.
