Victaulic has developed its FireLock™ IGS Style V9 Sprinkler Coupling and line of FireLock IGS grooved sprinklers. The sprinkler is UL-listed and FM-approved. Created to replace threads on both outlets and sprinklers, the company says this mechanical connection redefines sprinkler system design and installation in exposed applications, particularly the storage and warehouse market. The coupling has one-bolt, is captured onto sprinklers with a connection size of .5-in, .75-in, or 1-in, and transitions to 1-in allowing for the standardization of 1-in IGS outlets. The sprinkler and coupling arrive on site pre-assembled, with no loose parts and require no preparation before installation, also known as Installation-Ready™ technology that Victaulic introduced in 2005.
