    Lift-Off Cover

    Hinged Cover

    Protect your people and parts from explosive risks in areas with flammable gases, combustible dust, and ignitable fibers. These NEC-rated enclosures are often used to shield motor controls, power supplies, and wiring in plants that handle or make fuel, bulk powders, and chemicals. Plus, they lock out water to keep your electrical components dry.
    Lift-Off Cover—The removable, screw-secured cover is best for full access during setup or service, but not for frequent entry.
    Hinged Cover—The cover swings open for fast, frequent access and remains attached to prevent drops or loss.
    Aluminum—Best for housing sensors and other sensitive electronics where interference is a concern, these enclosures block wireless and radio signals. They’re also a rust-resistant alternative to stainless steel in wet areas.
