This is a 24 x 24 x 6 deep enclosure, made of 316 Stainless steel. It was mounted on an overpass along with 6 similar units. Roadways are very corrosive environments, and we wanted to offer the longest possible life span. However, stainless steel, when it’s new can be very reflective. So these units were painted an off white colour, to help them blend into the overpass railing system.
