Follow these two easy steps:
- Remove the auger from the driver and carefully measure the X and Y dimensions of the Kelly Bar. (See Kelly Bar Sizing Diagram to right)
- Match the shape of the Kelly Bar and the X and Y dimensions with the Kelly Bar Adapter charts below. The Y dimension on the Kelly Bar Adapter must be equal to or greater than the Y dimension on the intended Kelly Bar.
CHANCE anchor installing tools are provided with appropriate bolt circles for the expected service. The torque limitations for the two standard bolt circles are given below. Never exceed the rated torque of any Chance installing tool.
