Irwin Industrial Tools offers the Vise-Grip quick adjusting wrench. IRWIN has replaced the clumsy thumbwheel with a lever that adjusts the jaw 2X faster with a single motion. Unlike traditional wrenches, it will not strip nuts, bolts, or fasteners because the jaw locks securely into place. The grooved internal jaw slides forward manually for quick, one-handed sizing and locks in place for leverage and repeated use. It is available in metric and SAE versions and all models are backed by the Irwin Lifetime Guarantee. For more information, call (800) GO IRWIN or visit www.irwin.com.
