Why You Need It
Wrench Man™ Was designed and built to help break loose extremely tight fasteners where you can't fit an ordinary socket. Wrench Man™ will not slip off or twist during use. This means no more busted knuckles from interlocking wrenches or slipping a pipe over the jaw of an open end wrench. Wrench Man™ Was built by a Mechanic for Mechanics.
What Is Wrench Man™?
Wrench Man™ is a 1/2 inch drive tool that attaches to a ratchet or breaker bar and is then hooked on to a box end wrench. This extends the length of the wrench for increased leverage whether you are tightening or loosening that stubborn fastener.
