Introduction
The Detectable Fabric Innerduct is engineered for OSP/ISP projects prioritizing safety and compliance. Unlike non-detectable innerducts, which rely solely on visual identification, our duct incorporates metallic detection threads woven into its reinforced fabric, enabling precise location via standard ground-penetrating radar (GPR) or electromagnetic locators. This innovation eliminates the risk of accidental cable damage during roadwork, excavation, or maintenance—saving time and avoiding costly repairs. Ideal for urban, suburban, or utility corridors, it combines Telcordia GR-20-certified durability with compliance for AWWA, ICEA, and local regulations.
