The Klein Tools' Heavy-Duty Ratcheting Lineman's Wrench is great for utility work. Its 3/4-Inch, 13/16-Inch, 1-Inch and 1-1/8-Inch combination square socket works with the most common utility hardware. It also features two popular wrench sizes: 3/4-Inch and 9/16-Inch.
Klein Tools Lineman's Wrenches are forged from special bar steel and heat-treated for durability and long life. These wrenches are designed for use on heavy three-bolt guy clamps where clearance is limited. Each end has two different size openings, plus a hole at the larger end for turning-in standard pole steps.
