54mm Reducing Adapter (2″) from 78 Round

Straight forward to insert; simply push into the 78mm sleeve & use your Post Driver. To remove, insert a thin bar into the holes at the base of the adapter, stand on the bar & pull. Very easy to use, with no bolts or washers to lose.

To get the most effective use from the Post Driver, the Adapter size must be a snug fit for your Posts. We recommend the Adapter must be no more than 5-10mm larger than your Post. For shaped posts; squares / t-shapes etc the outer corners need to be within this capacity.

If you are unsure what adapter are right for you, please contact us for advice specific for your application.

The maximum size post that can be driven in is 4” (100mm) diameter.Our largest adapter is 107mm internal diameter. When the ground is very dry, compacted or stony, you will need to make a pilot hole for posts larger than 78mm. This can be either by hand using a Pilot-Bar, or mechanically using the Pilot Core Tool. Posts smaller than 78mm should not need a pilot hole. Ground conditions of Clay or Chalk may also require this method.
