- This device is an earthquake proof firefighting pipe material mainly installed in apartments,
houses, and shopping complexes.
-This pipe material is used to fix sprinkler heads that sprinkle water in case of a fire and is
installed on ceilings.
-It is firmer than the screw rotating type with a much lower error rate.
-The screw rotating type uses electric tools to move up and down, but our product does not use
tools and operates only manually.
-It can be installed two to three times faster, thus shortening the working time.
-It largely saves on labor cost making it highly popular in construction sites.
