Abstract
A multi-functional wrench having an adjustable construction that allows the nut or bolt engaging surfaces of the wrench to be located at different angles or positions relative to a handle in order to allow the wrench to be used in otherwise difficult to reach areas. The wrench optionally includes a secondary handle removably connected to a preferably arcuate, multi-functional wrench body that is, in turn, removably connectable to a desired wrench head which includes a work-engaging fitting. The multi-functional wrench has a body that is archial or curved in shape and includes at least one drive post or ratchet and a plurality of sockets that are useful for many applications. The wrench is particularly useful to manipulate the body of straight stop and angle stop compression valves connectable to plumbing under sinks, behind toilets and inside cabinets, as well as nuts and bolts.
