Seiho's TurboNozzle combines a stylish anodized aluminum finish with exceptionally high quality construction. The deep housing and inner concentric rings are designed specifically for those high volume long throw applications. The NT provides a distribution pattern more diffuse than our PK series, but not as much as the RHV/NR series. The aluminum and stainless steel design contribute to the NT's light weight so much so that it is easily installed and held in place by strong spring clips. No unsightly screws are necessary!*

*Note: NT & NP are designed for wall mounting. Screws must be used for ceiling mounting.
