Methods and apparatuses are disclosed with regard to a tool for actuating chain-operated assemblies. One embodiment includes a tool including an elongated member having a top, a bottom, and a length greater than a width. Further, the tool includes a first set of equidistantly spaced hooks in a linear arrangement along the length, wherein the first set is located closer to the top than the bottom. When one or more hooks engage the chain of the chainwheel, a further feature enables the tool to lock down on those engaged chains, and, thereby, provide safer pulling and pushing to open and close the chain-operated assembly. Further still, the tool includes at least one handle in an offset, parallel position relative to the first set, wherein the at least one handle may be located closer to the bottom than the top.
