SprinkFLEX Commercial Sprinkler Assembly

The SprinkFLEX® stainless steel hose and the SprinkFLEX® mounting bracket are particularly suited for use in suspended ceiling applications making the installation quick and easy saving time and labor. The SprinkFLEX® hose and mounting bracket can also be attached to studs and installed in gypsum board ceiling systems.

Each SprinkFLEX® drop assembly comes with one stainless steel flexible hose (braided or unbraided), one branch line connection nipple, one sprinkler reducing nipple and the mounting bracket system. The SprinkFLEX® hose is offered in lengths from 28″ – 71″ with reducing fittings for 1/2″ or 3/4″ sprinkler heads. The non-braided models are UL Listed. The braided models are FM approved and UL Listed.

The SprinkFLEX® one piece mounting bracket comes fully assembled out of the carton for quick and easy installation. The mounting bracket has an open hub making it easy to insert the reducing fitting into the mounting bracket. The SprinkFLEX® mounting brackets are available in both 24″ and 48″ lengths with no tools required for installation. The mounting bracket allows the sprinkler head to be located anywhere within the ceiling with reference marks in the center for ease of installation without the need for measuring. The system is fully compatible with all sprinkler types including pendant, semi-recessed and concealed sprinkler heads.

The SprinkFLEX® products offer a cost effective solution for the installation of fire sprinkler systems which result in a quick and easy way to connect the sprinkler heads to the branch lines.
