ESD Conductive Dividable Grid Containers - Protect your electronic components from typical electromagnetic interference (EMI), electrostatic or induced fields with these conductive polypropylene dividable grid containers. Made of conductive material that provides a barrier which these fields which cannot penetrate and prevents build up of electrostatic charge. Containers, dividers, and covers are permanently conductive and are unaffected by washing and normal cleaners. Containers have a load capacity of 100 lbs. Dividers available to customize your box into compartments at 1-1/8" intervals. Snap on covers protect contents from dust or damage. Molded from a carbon filled copolymer polypropylene material with a electrostatic decay rate at less than 0.1 second that meets military specification MI-B-81075B. Its surface resistivity is less than 105 Ohms-per square. Optional label holders to help provide fast identification. Always be sure all units are properly grounded according to your use.
