NOS 3M 8501 Portable Static-Dissipative Field Service Kit. Unused surplus. Original 3M instruction sheet and ground-cord assembly included. Stored in a clear poly bag, not a retail carton. Light storage marks possible on the vinyl; snaps, stitching, and hardware are intact.

Made for field service of static-sensitive electronics. Unfold the mat next to the equipment, snap the common-point cord to the mat, connect the wrist strap, and clip the banana-plug lead to ground. Charge on the technician and on conductive parts laid on the mat drains to ground. Dissipative surface (not highly conductive) reduces sparking/shorting and limits drain from battery packs. Folds to fit a tool case. Two sewn pockets store the cords.

Included, as shown:

• Red static-dissipative work surface, black edge binding, red stitch, female snap
• 3M instruction sheet: “Installation Instructions 8501 Portable Static-Dissipative Field Service Kit”
• Ground cord assembly in bag: coiled cords, center snap for the mat, banana plug, alligator clip
• Wrist-strap hardware in the same bag
