We build these exclusive P&S receptacles with no ferrous metal, so they are perfect for high-magnetic field environments such as magnetic-resonance imaging (MRI) suites. With the same basic design as our standard Extra Heavy-Duty Receptacles, they are extremely durable. Features include a solid brass strap for an excellent ground path to the box, plus brass terminal and installation screws.
Additional Info: Extra-Heavy Duty, Operating Temperature: -40 to 60 deg C
