Detectable underground warning tape makes locating non-metallic utility lines easy and convenient. Detectable warning tape also acts as a safety warning against inadvertent intrusion or dig-ins to the cable right of way. All tapes are made of a tough poly / foil / poly blend of materials. Hand stretch wrap is designed to ease the task of bundling or wrapping objects in the shipping and manufacturing areas.
