Product Identity: FireLock™ IGS™ Installation-Ready™ Style V9 Sprinkler Coupling.

Description: Rigid grooved coupling and reducing coupling specifically for joining IGS™ grooved sprinklers to IGS™ grooved sprinkler outlets.

FM Approval Status: FM Approved.

Hazard Involved: The Style V9 Sprinkler Coupling is secured on one side using a single cap screw and locking nut while the other side is hinged. In couplings with affected cap screws, if the cap screw breaks, the coupling will separate and release the coupling and connected sprinkler from the system piping and result in water discharge from the system outlet. Sprinklers installed using the Style V9 coupling will still perform as intended in response to fire.
