    Tamper-Resistant Outlet—Tamper-resistant outlets have internal shutters, which prevent the insertion of foreign objects and accidental contact with power.
    Sure-Grip Outlet—Sure-grip outlets, also known as hospital-grade outlets, have an extra-tight fit when mated to remain secure in high-vibration environments.
