The Keson Foil Underground Detectable Tape features a color band and black ink imprint that is encapsulated in the tape. The ink does not extend to the edges, giving maximum bond between the piles. The aluminum makes it an ideal choice for locating nonmetalic lines. The durable tape is constructed with prime resin and tolerates -94 degrees to 200 degree temperature range. THe tape meets OSHA regulation 1926-956 (c) (I) covering location of underground utility lines.
