In the event that the arms of a 1/2" NPT fire sprinkler head are broken off, this attachment can be placed on the Shutgun so that it can shut off the damaged sprinkler head.
Caution: Do not use this attachment on un-damaged fire sprinkler heads. When the attachment is in place, the fusible link may not work on some types of fire sprinkler heads.
Note: Shutgun not included.
This site is devoted to the Shutgun, fire sprinkler shut off tool for building managers, construction, hotels and other commercial or storage facilities. An activated fire sprinkler head can cost $1,000s in damage, repairs and delays. Shutgun stops water flowing from activated sprinkler heads immediately. One on every floor - in every tool box. Don't get caught without one.
