Foundation Drive Tool Ordering Information

Kelly Bar Adapters

Selecting the correct Kelly Bar Adapter is key to building
a proper Drive String.

Follow these two easy steps:
1) Remove the auger from the driver and carefully measure
the X and Y dimensions of the Kelly Bar.

2) 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.
