- Strength & Composition -

Using FLEXONE 25 saves time and cost because the system can be installed in false ceilings without cutting and threading pipes associated with installing a drop, arm-over, and elbows.

FLEXONE 25 makes it possible to test and charge the system with water before installing the ceiling grid. After the ceiling grid is in position, the FLEXONE 25 can be reshaped to suit the final sprinkler location without draining the system.

FLEXONE 25 is installed quickly without large and expensive tools. Ideal applications include offices, schools, libraries, hospitals, and shopping complexes.
