WrightGrip anti-slip design
WrightGrip is an innovative, high-strength, anti-slip design on Wright Tool Company’s open-end wrenches. The new design is standard on all Wright Tool open-end and combination wrenches in sizes up to 1 1/4 inches. The design ensures that the open-end wrench fits more snugly on the fastener, preventing the jaws from spreading and keeping the wrench from slipping. It has up to 50 percent more strength than traditional Wright open-end wrenches and is up to 80 percent stronger than comparable competing wrenches.
