See All Products

Reliable extended coverage sprinklers are designed to protect larger areas than specified by installation rules for standard spray sprinklers. Reliable extended coverage sprinklers are approved to protect light, ordinary, and extra hazard occupancies, and are available in a wide variety of finishes, temperatures, and styles.  

Reliable extended coverage sprinklers may reduce both material and installation costs by reducing the number of sprinklers, branch lines, fittings, and installation time. 

For more information regarding the proper handling, storage, and installation of Reliable fire sprinklers, please see Caution Sheet 310.
