ABSTRACT:
A tool and a method for installing a sprinkler head in a threaded fitting of a fire suppression system is disclosed. The sprinkler head is protected by a cover. The tool is formed from an elongated body having a cavity that is sized to receive the cover. One end of the body interfaces with a wrench, the other end has one or more axially extending slots sized to receive the fingers of a torque plate affixed to the sprinkler head. The sprinkler head has a threaded nipple that engages the threaded fitting. The nipple is engaged with the fitting and torque is applied to it by engaging the slots of the tool with the fingers and turning the tool with the wrench. The tool has an external index allowing the sprinkler head to be angularly oriented to direct its discharge stream.
