The Industrial Brass Monitor – 3-1/4" Waterway, 1250 GPM is a rugged, high-capacity monitor engineered for demanding marine, offshore, industrial, and corrosive-environment firefighting applications. Featuring a full 3-1/4" waterway and efficient internal flow design, this monitor delivers up to 1250 GPM while minimizing friction loss and maximizing stream performance.

Constructed from corrosion-resistant brass with a durable red powder-coated finish, this monitor is designed for long-term reliability and minimal maintenance. Cast-in turning vanes improve flow efficiency, while positive friction locks on both horizontal and vertical travel allow operators to securely position the monitor during operation. Its compact, low-profile design and 360° rotational capability provide exceptional maneuverability and operational flexibility in challenging environments.
