Erection Wrench
  • Drop-forged from select alloy steel to withstand high-leverage and heavy loads.
  • Extra-heavy-duty head area gives maximum strength and durability.
  • Wrench handle features an extra-deep offset to provide additional hand-clearance without sacrificing tightening power.
  • Continuous taper of handle makes lining-up bolt holes easy, allows use on a range of bolt-hole sizes without binding.
  • Extra-large hub area allows use on larger diameter holes than possible with most other wrenches.
  • Available in heavy, regular and utility nut sizes.
  • Catalog number, bolt size and nominal opening size are stamped on every wrench for easy identification.
  • American Bridge Design.
