Abstract: A tool for setting a board on a joist, the tool includes a generally vertically extending elongated bar and a hook member attached to a lower end of the bar. The lower end and the hook member form an engaging assembly for removably engaging the lower end portion of the bar to the joist. The hook member includes a lower member attached to and extending laterally outward from a lower end portion of the bar and a guiding member attached to and extending generally vertical upward from an outer end of said the lower member. At least one pointed member is fixedly attached to and extends vertically upward from the upper surface of the first member. The pointed member includes a pointed upper end to engage the joist and establish a fulcrum point between the bar and the joist. After the tool has been engaged with the joist the bar may be rotated to contact the board and urge the board into a desired position relative to the joist.
