To adjust the jaws of Crescent's RapidSlide Adjustable Wrench, one merely moves the button-slider on the handle either up or down, instead of having to finger-twist a spiral-thread knob. The adjusting mechanism is a rod with spiral grooves inside the handle; the slide-button rotates the rod which opens and closes the jaws. The tool is made of forged steel with a chrome finish, has a jaw capacity of 1 1/4 inches (10-inch model) or 1 inch (8-inch model), a wide handle for increased leverage, and a SAE/metric size indicator marked on the jaw.
