3M Portable Labelers, manufactured by DYMO allow customers to quickly and easily mark or label electrical machinery, panels, wire, or other devices. We are offering two labelers, the PL300 and PL100 each suited for a specific market tier, with corresponding label stock for various environments and surface types. All three printers will print on heat shrink, and have exclusive "hot key" technology. 3M Portable Labeler Refill Cartridges come filled with vinyl, polyester, nylon, heat shrink or non-adhesive labels.
