Upright Sprinklers
Upright Sprinklers are fire-suppression devices designed for installation on piping where obstructions or open structural elements prevent the use of pendent sprinklers.
The deflector is positioned above the orifice, allowing water to discharge upward and then spread in a circular pattern to provide uniform coverage across open areas.
These sprinklers are widely used in warehouses, parking garages, industrial plants, manufacturing facilities and spaces with exposed ceilings. Available in multiple temperature ratings, response types, K-factors and finishes to fit diverse fire-protection system designs.
