In combination with a bull float, hand trowel, groover, finisher, and the like, an elongated handle, which adjustably mounts through a bracket with the attachment means provided upon the upper portion of such a finishing tool, with the handle means incorporating a housing, spring biasing a detent therein, which is normally held into locking engagement with the tool bracket, as when the handle is threadedly engaged within its housing, or which can be readjusted into various other angular dispositions, for the convenience of the concrete finisher, by partially withdrawing the handle from its threaded engagement within its housing, thereby disengaging its detent from the bracket, to accommodate and faciliate the undertaking of such pivotal movement for the handle, during its readjustment.
