ABSTRACT:
A wrench that combines the narrow profile of an Open End with the adjustability of a large in profile Adjustable wrench and that meets the "Wrench Clearances for Open End Engineers Wrench 15.degree.", (from SAE Aeronautical Drafting Manual). The turnbuckle principle linked to wedge pins that move through crossing slots provide for parallel movement of two slidably connected wrench-halves. Actuation mechanism is shifted from the standard head location to the intermediate portion of the handle and the ends of the wrench are designed for turning two consecutive size ranges.
