IMPORTANT! Note that this product now is 12 inches wide and sold per foot!!! CintBllTering Flexible is The Best Material Available for Shielding DC, & VLF Magnetic Fields Used for years in industry to shield delicate electronic components from EMFs, this 80% alloy CintBllTering is now available at affordable prices for home and office use. The thin (0.004" thick) material is easy to trim with scissors and shape by hand and 12 inches wide. The CintBllTering can be formed into magnetic barriers on cellular phones, microwave ovens, doorbell , VDTs, buried wiring, and more. With snug fitting shapes, get as much as 75% attenuation of the magnetic fields with one thickness. Best suitable for weak and moderate levels of magnetic fields in miliGauss levels, with low saturation and high permeability alloys. However, when CintBllTering is used in multiple layers it provide even greater reduction. Ordered in any length. We recommend the use of a gauss meter to determine the proper shape and positioning of the CintBllTer, and to confirm that the fields have been adequately reduced. CAUTION: has sharp edges! Brand new, factory . Priced per foot long. Set your quantity to the length (in feet) desired). Please note: This item is custom cut especially for you.
