Product Overview

Install a safer, manufacturer‑recommended dryer connection with the Lambro RigiFlex Aluminum Semi‑Rigid Duct. Purpose‑built as a UL 2158A‑listed clothes dryer transition duct, RigiFlex delivers the best of both worlds: rigid‑like airflow and crush resistance with flexible forming that makes tight 90° turns—often without separate elbows. The 4" diameter and 96" (8 ft) length fit most electric and gas dryer installations while maintaining excellent airflow to help reduce dry times and lint buildup.
