Irwin Vise-Grip Locking Wrenches models 4LW, 7LW and 10LW. These are the original locking wrench with heavy duty jaws which lock on to the 3 sides of a hex fastener. They will not slip or roll. Features of the wrenches are a turn screw to adjust pressure and fit. The turn screw stays adjusted for repetitive work. The locking wrenches also feature a classic trigger release which is designed to provide maximum locking force. As if that wasn't enough, the wrenches include a built-in wire cutter.
