Safe. Flexible. Fire-Resistant.
Infra Pipes’ Plenum & Riser raceways provide reliable cable protection in residential and commercial buildings—delivering strength, flexibility, and fire resistance where it matters most. Plenum & Riser was formerly produced by Endot.
Engineered for Building Safety
Designed with a corrugated profile, Plenum & Riser products provide a low-friction pathway for installing and protecting fiber optic and electrical cables. Plenum raceways are manufactured from PVDF resin and engineered for one-floor installations exposed to HVAC airflow, while Riser products are produced from durable nylon to safely route cables floor-to-floor in vertical building shafts.
Advantages That Matter
Plenum & Riser conduits offer key performance benefits for building applications:
Fire-resistant and UL-listed for safety
Corrugated design for easy cable pulling
Non-metallic and lightweight for handling ease
Flexible and kink-resistant
Durable construction for long service life
Available in standard orange or white, with custom colors on request
Protecting Connections Indoors
Plenum & Riser raceways combine flexibility, safety, and reliability to simplify installation while protecting critical cables in sensitive indoor environments. Fire-resistant properties, pre-installed UL pull lines, and multiple sizing options make them a trusted solution for contractors, engineers, and building owners.
