For electricians, network techs, or anyone who needs to organize a mess of wires. This is a Panduit P1 cassette of self-laminated wire labels. You get 200 labels on a roll that fits into a compatible Panduit handheld label printer. The labels are vinyl and have a white area where you print your text (like 'Circuit A', 'Network Jack 1'), and then a clear plastic tail that wraps around the wire to protect the print. They're durable, weather-resistant, and perfect for identifying wires in panels, data centers, or network closets. The cassette includes both the label material and the printing ribbon, so it's an all-in-one cartridge. A professional-grade tool for keeping your wiring projects neat and understandable.
