Staticide Snap Fasteners provide a grounding point for rubber and vinyl static dissipative mats. Once the snap fastener is installed on the ESD mat, grounding cords equipped with a 10mm stud will clip into place. For 2-layer mats, the flat eyelet base offers good contact with the bottom conductive layer. The middle post can accommodate mat thicknesses up to 3mm (0.118”). Compatible for use with the Staticide 8802 Pres-N-Snap Tool.
