The FlexHead® Drop Nipple Model uses traditional Unistrut® to secure the FlexHead® sprinkler hose to the building structure. The flexible hose is attached to a drop nipple with reducer during final fit-up and is also compatible with adjustable drop nipples. This model is perfect for applications where you have a concrete deck above the ceiling that can be used to secure the flexible hose to the building structure. This configuration allows the installer to attach the Unistrut® in the general location of the sprinkler head during the rough installation.
The Unistrut® is initially attached to the building structure on one side and can be rotated 360 degrees while the flexible hose can be adjusted along the length of the Unistrut® to get perfect sprinkler head placement without any reconfiguration of sprinkler piping. These models are designed for use in commercial suspended ceilings and Sheetrock ceilings.
