Web Exclusive NFPA Product Review-Ceiling Sprinkler
The FlexHead commercial ceiling sprinkler features flexible stainless steel hose (rated up to 300 psi) to connect sprinkler heads to the branch line, eliminating hard-pipe armovers and simplifying installation. With no rigid joints between the branch line and the head, the flexible connection is impervious to building motion, even in seismically active areas. And it remains watertight under the most rigorous conditions. Hoses are available in 2-foot to 6-foot lengths and can easily be fitted with any standard sprinkler head. FlexHead Industries.
