Seiho's Model NTX-R Spiral Duct Mounted Aluminum TurboNozzle offers excellent architectural styling for directional control in supply applications. Designed specifically for direct mounting to exposed, round, sheet metal (spiral or k-d) ductwork, it provides an integral, readily-accessible, airflow adjustment in its installed position. The heavy-gauge anodized, aluminum and stainless steel construction is corrosion-resistant for years of service. The aluminum finish integrates seamlessly with the galvanized finish of exposed duct systems.
