The Stanley Proto Torque Multiplier Display Wrench measures applied torque directly at the fastener, with an accuracy of plus or minus 1 percent. The tool, which is placed between the multiplier and the fastener, is designed to ensure that the proper final torque is applied to the fastener.
The display wrench has a 1-inch drive and is available in two torque ranges: Model J6349A has a range of 100-1,000 lb.-ft., while model J6352 has a range of 200-2,000 lb.-ft. Both are 24 inches in length.
