This backflow enclosure is a vandal and weather resistant enclosure formed entirely of marine grade 5052-H32 aluminum alloy, with a wall thickness of 1/8 inch. The main housing is a solid sheet construction punched on the sides with a rectangular pattern for viewing backflow operation. The mounting base plate is formed of powder coated stainless steel and secured with provided anchor plates into wet concrete or anchor bolts a minimum of 2 inches deep into cured concrete . The center split design allows enclosure sides to swing out, pivoting on the mounting hardware at each end. The full release locking mechanism is a stainless steel cross bar that includes provisions for a padlock. Insulated Polar Bearier bag protects the backflow device from freezing temperatures. Polar Bearier bags provide an R19 insulation rating using Radiant Barrier Foil (RBF) inserted between acrylic polyester and air bubble pack. The Polar Bearier bag is also impervious to moisture.
