Abstract: A fixture installation tool provides for installation of a fixture on a mounting bracket adjacent a surface. The fixture installation tool includes at least one elongate support post removably attached to the mounting bracket and oriented such that the elongate support post extends to a distal end away from the surface, the elongate support post having a diameter such that the elongate support post slidably fits through a mounting hole of the fixture and at least one removable stop located on the distal end of the at least one elongate support post, the removable stop sized to prevent the fixture from sliding off of the at least one elongate support post. The at least one elongate support post is removably attached to the mounting bracket such that the fixture installation tool supports the fixture in proximity to the surface for wiring of the fixture.
