Abstract: The present invention is an apparatus to facilitate the installation and replacement of mechanical devices, particularly plumbing compression fittings such as an angle-stop valve. The wrench has a first member that includes an open-end wrench and associated jaw surface and a hollow handle extending therefrom. A second member also includes an open-end wrench and a handle extending therefrom, the handle of the second member being of a diameter small enough to slidably fit within the handle of the first member. The handles of the first and second members preferably including mating means so as to enable the temporary locking of the two members for use and or storage of the two-piece wrench apparatus. The handle of the second member further includes a lug extending therefrom and having a certain size and shape so as to allow the lug end of the wrench to engage an inner diameter of the angle-stop valve during its installation.
