New sprinkler connection piping Flexible Sprinkler Drops

The Genie System new sprinkler piping is designed to significantly reduce wages and assembly costs.
By essentially blocking pipe cutting and mid-pipe connections, you can save time and money efficiently.

The Genie System new sprinkler connection piping is 700/1000/1200/1500 / 1800mm hose length Braid and Unbraid type which can be assembled with various kinds of brackets on the top and front part of ceiling and wall structure. Especially, it can be installed on structure T-BAR, metal ornaments, Hat channel, wood beams, concrete sidewalls and so on. The Genie System is certified for use in commercial hotels, restaurants, cultural centers, entertainment, educational institutions, public institutions, athletic facilities, and religious buildings.
