The fusible link may require replacement due to exposure to the heat of a fire that caused the Shutgun to release. Mechanical damage may also cause the fusible link to require replacement.
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.
