Victaulic’s new FireLock™ Installation-Ready™ Style 109 Rigid Coupling extends one-bolt Installation-Ready technology to 1¼ in. to 4 in. sizes. Previously available to 1 in., the one-bolt design brings increased efficiencies, safety and value to fire protection systems. Rated up to 365 psi with no torque requirement for installation, the Style 109 Rigid Coupling can be joined up to six times faster than traditional couplings and allows for visual inspection of a single bolt pad, adding confidence in a leak-free installation. The two-piece housing is easily handled and installed overhead, while the one-bolt design eliminates alternating during tightening.
