This is a adjustable wrench, Wright Tool 4, in opens to 11/16 inch, chrome finish. Wright hot-forges its wrenches and drive tools from alloy steel at its own Ohio plant rather than buying forgings in, and the broaching is cut to hold on the flats of the fastener rather than the corners.
One wrench that fits a range of fastener sizes, for service calls and odd-size fittings where carrying the full set is not practical.
Wright Tool has hot-forged hand tools in Barberton, Ohio since 1927, and publishes a per-SKU disclosure for the small share of its line that is not US-made.
