Standard, Detectable, Plenum & Riser. Fabric inner duct refer to the different conduit

application sizes and number of cells/pathways per product type. Most product lines are

offered in all of the product type variations.









A versatile solution for the complex problems faced by today’s engineers, contractors and network providers. Manufactured from internally designed and produced materials, this model yields superior performance over existing rigid innerduct.

Standard fabric inner duct is the primary product line used in common outside plant applications, including long lines, under-bridge; road, river and rail borings; under streets and all the way to building entrance points. Standard fabric inner duct is available for conduit sizes ranging from 1″ to 4″, and in 1-, 2- and 3-cell configurations – – giving you the flexibility to choose the right product for your system and applications.
