ULTRALINE® AMU Series FRP (fiberglass reinforced polyester) enclosures come standard with patented mounting options, including an out-of-the-box mounting flange or adjustable mounting feet to cover various mounting configurations. Featuring molded latch keepers, a tongue and groove seal design, and a flange design that can be retrofit to competition, ULTRALINE is the ultimate in nonmetallic enclosures. A clear polycarbonate cover option is also available for instrumentation applications where critical electronic equipment must be visible and protected from the elements.
