Viking FSC Flexible Sprinkler Assemblies are offered with a wide variety of Viking Commercial sprinklers, and are factory-installed onto the outlet fitting of the FSC flexible sprinkler connection. The FSC line features both a UL Listed unbraided flexible connection (Model FSC-25U) and an FM Approved braided flexible connection (Model FSC-28B). Viking’s FSC Flexible Sprinkler Connections also feature a fully assembled installation bracket that is ready to install out of the box, with no loose parts. These pre-assembled FSC sprinkler assemblies are 100% pressure tested by Viking, and allow generous amounts of vertical and lateral adjustment. Viking FSC sprinklers are pre-packaged (10) units per carton. Refer to Table 1 in the Technical Datasheet for sprinklers available pre-assembled as Flexible Sprinkler Connection Assemblies.
