The Klein 3222 3/4-Inch Erection Wrench is a great addition to your Klein tool collection. The American Bridge designed wrench is forged from select alloy steel to withstand high-leverage and heavy loads. The extra-heavy-duty head area gives maximum strength and durability. The continuous taper of handle makes lining-up bolt holes easy and works on a range of bolt and/or hole sizes without binding. The extra-large hub area works on larger diameter holes than other wrenches.
