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.
