This high-grade stainless-steel hat is not only corrosion-resistant but also highly conductive making it the perfect radiation blocker at homes, offices, schools and other places with EMF radiation incidence.
• Effective Anti-Radiation Fabric - Most homes and offices use a smart meter, an electronic device that records electrical consumption. The device then transmits this data to the electrical supplier for billing. Smart meter transmittal gives off radio frequencies (RFs) which can be harmful to health. The cover blocks off up to 98% of the radiation emitted by this electronic device.
• Easy Installation With Patent Pending Magnetic Holders - The EMF DEFENDER smart meter EMF/RF shield uses patent pending magnetic holders to keep shield in place, the device can fit most, but not all, meters sold across the US and Canada. Measures 7 inches in diameter at the base. Install on your own: slide the cover in place over the meter's glass portion and adjust accordingly for a tight fit. No assembly and complicated installations required.
• Sturdy And Weatherproof - Most smart meters are located outdoors that is why the RF smart meter cover is created with high grade, spot-welded 316 stainless steel meshing. This type of steel material has high corrosion resistance giving the smart meter blocker its property of durability. It is sure to withstand all weather conditions. Please note there may be irregularities in the cut and color of the metal caging as a result of the welding process
• Stay Safe And Healthy! - Ringing in the ears, unexplainable headaches, chronic migraine despite having no underlying conditions - these are just some of the suspected harmful effects of EMF, RF radiation on people's health.
