Lennox Y3392 – DiversiTech 230-FB454 SpeediChannel 45 Degree Flat Bend is a low-profile duct routing accessory designed for clean, professional mini-split and HVAC line set installations. This 4-inch flat bend allows the SpeediChannel system to transition smoothly around corners at a 45-degree angle while maintaining a neat appearance and proper line set clearance.

Manufactured from durable, UV-resistant PVC, this flat bend is suitable for both indoor and outdoor applications and matches the natural color of standard SpeediChannel raceway components. It snaps easily into compatible 4-inch SpeediChannel sections, helping installers maintain consistent alignment, reduce visible line exposure, and protect refrigerant lines, drain hoses, and control wiring.

Commonly used in ductless mini-split installations, heat pump systems, and light commercial HVAC applications, the DiversiTech 230-FB454 flat bend helps deliver a clean, code-friendly finish while improving overall installation aesthetics.
