Warning TapesSentry Line™ Detectable tapes may be locatedby inductive or conductive methods
utilizing most standard pipe and cable locators. Color coded for application and non-adhesively laminated, Sentry Line tapes are colorfast and chemically inert for lifetime stability underground and have been successfully located more than twenty years after internment. Also available in reinforced and non-reinforced grades.

The top of the line in detectable tapes. Superior tensile strength and puncture resistance allows it to withstand the rigors of being plowed in without breaking. This also makes it ideal for Detectable Marking Tapes situations where site conditions are difficult.

Sentry Line™ Detectable Similar to above but with lower tensile strength and puncture resistance. Terra Clips are used to electrically connect one roll of detectable tape to the next and for connecting lengths of tape placed over laterals or tees. These must be installed at the time the tape is buried if the location method will be conductive but they can also be used to enhance continuous inductive location. Terra Clips are packaged in bags suitable for making 5 splices or bulk packaged.

Extra Stretch™ underground marking tape
can help prevent the high cost of accidental
line damage and the inconvenience of
service interruptions.

Performance proven the world over for protecting telecommunications, electric, gas and other utilities. Extra Stretch™ is unsurpassed in its balance of high tensile strength, puncture resistance and excellent elongation properties. This unique combination of properties allows it to stretch above grade level in one continuous piece, ensuring jobsite personnel and machine operators will be alerted to stop digging immediately and contact the appropriate authorities. Easy to install, Extra Stretch™ is available in a variety of imprints, colors and sizes to meet your specific requirements.
