Fire sprinkler tools like the concealed head Shutgun provide consumers with a cost-effective way to stop accidental discharge from sprinkler heads. These replacement probes allow an existing concealed head Shutgun to be used with either 1/2 in. (12.7 mm) or 3/4 in. (19.1 mm) NPT concealed or recessed fire sprinkler heads. Crafted using cast aluminum and rubber and manufactured Technicraft, the creators of the official Shutgun, these attachments are simple to install and even easier to use.

What is a concealed head Shutgun?

Concealed Head Shutgun is a fire sprinkler shutoff tool for concealed and recessed fire sprinkler heads. This fire sprinkler stopper gun is equipped with a fusible link thermal element that activates at 164F (73C). In essence, these tools act as a surrogate fire sprinkler head until a replacement can be installed.

The Concealed Head Shutgun features extended probes that are long enough to reach inside the opening of a concealed or recessed sprinkler in a wall or ceiling, helping users stop an activated sprinkler head quickly.

Shutgun's design allows for the closure of a wide range of sprinklers, including concealed pendent fire sprinklers. Without a fire sprinkler stopper, sprinkler discharge can only be stopped at the main valve or a local shutoff valve. Fire code may require personnel to patrol the building or even evacuate until the broken head is replaced.

The concealed head Shutgun stops water damage caused by accidental fire sprinkler discharge: vandalism, human error, and industrial accidents can lead to mold, mildew, damaged carpets, and a host of other expensive issues. This fire sprinkler shutoff device is a must-have tool for condos, hotels, office buildings, and anyone who works in close proximity to fire sprinklers.

How do I apply the attachment?

To apply this attachment piece to the Shutgun sprinkler stopper:

  • Determine the size of probe needed. The smaller rubber probe is for 1/2 in. sprinkler heads, the larger rubber is for 3/4 in. sprinkler heads. If you are unsure, it may be advisable to use the 1/2 in. probe, which works with the most commonly used sprinkler head size.
  • Remove the nut from the probe and leave the washer attached.
  • Screw into the pusher rod until snug. Do not overtighten, which may deform the rubber
