An open-ended wrench characterized by having a ratcheting head at each end which is rotatively supported or held directly by the elongated main body having pawls which are spreadable and may be disengaged from the teeth on the ratchet wrench head allowing it to freely spin and disengage from a tightened hose assembly. A partially exposed sprocket at each ratchet head allows rotation up to 55 degrees in either direction from its starting point, enabling it to be engaged with, or disengaged from, a nut, bolt, or hose-fitting more easily in a tight space. This wrench comprises an elongated main body having a 'C'-shaped 'C'-channel at each end forming an annular recess around and rotatively holding the corresponding flange on the outer periphery of the ratchet wrench head. A pair of pawls attached to a mounting pin in the elongated main body extend into the annular recess at diametrically opposed points relative to the corresponding ratchet wrench head may be easily spread with the pull of a spring-loaded button located toward each end of the elongated main body. |
