The FlexHead® Low-Profile Model uses traditional Anvil Strut® Channel to secure the FlexHead® sprinkler hose to the building structure. This model is perfect for applications where you have very limited space and 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 Anvil Strut Channel in the general location of the sprinkler head and adjust it later once the final fit-up is ready to be completed.
