The VIM Tools 15" Wrench Extender, No. WE15, is designed to protect wrenches from damage due to users hammering them or latching them together to increase leverage. It allows for added leverage and more torque when breaking loose stubborn bolts. It's also ideal for getting to hard-to-reach areas. The handle is designed ergonomically to allow for better gripping when breaking bolts loose. The patented wrench extender works with almost any wrench and comes with a limited lifetime warranty.
