    Interference-Shielding Expandable Wire Sleeving

    Protect wire and cable from signal distortion caused by nearby equipment and devices. Expandable, this sleeving stretches to fit over items for easy installation, then tightens around its contents for a secure fit. The braided construction permits heat and moisture to dissipate. This sleeving is also used to insulate and organize wire and cable. Cut to size with sheet metal snips.
    Tin-Plated Copper
    Image of Product. Front orientation. Wire Sleeving. Interference-Shielding Expandable Wire Sleeving, Tin-Plated Copper.
    Copper sleeving is more conductive than aluminum sleeving, so it resists more signal interference.
