The SCS formerly 3M 8204 ESD-Safe Blue Floor Mat Kit floor mats come with a three-layer construction. The top layer is durable static dissipative vinyl, which has sufficiently low resistance to discharge static-laden conductors, yet will help prevent the shorting of pins on the backs of printed circuit boards laid on the mat. The middle layer is a highly-conductive scrim that provides the main discharge path to ground, and the bottom layer is static-dissipative foam, providing a durable nonskid cushion.
Includes one 15 ft. (4.6 m) Ground Cord 3040 and two Snap Fasteners 3050 (installed).
