A ratchet wrench rotatably operable in a vertical plane for removal and installation of a fastener includes a body with a shank portion and outwardly extending first and second member forming an offset in such body. A first ratchet mechanism disposed in a first head of the wrench attached to the first member and a second ratchet mechanism disposed in a second head attached to the second member are identical except for rotational direction enabling to remove the fastener with one end and install the fastener with the other end of the wrench.
