Abstract: The invention is a system used to effectively install and remove dry sprinkler pendent heads. The system includes a barrel that cooperates with an associated fitting configured about the exterior of the outer casing tube of a pendent sprinkler. Specifically, the barrel includes a slot channel and extension sized and shaped to house one or more fitting teeth to releasably join the fitting and the barrel. Once joined, the barrel can be rotated to thereby install or remove an attached pendent sprinkler.
