Size
Internal diameter of 52x52mm. This adapter is suitable for driving 2" square posts.
Easy Fitting
Use a 6mm hex key to unscrew the 8 bolts & locking washers. Slide the current tube off the base of the Post Driver. Slide the new Adapter into its place and attach using the same bolts and washers. Remember to use a Locking Compound on the screw threads to stop them vibrating out.
What adapters do I need?
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.
What is the maximum capacity of the machine?
The maximum capacity of the machine is 107mm round 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 either our Pilot Core Tool or an earth Auger. Posts smaller than 78mm should not need a pilot hole unless the ground is very hard.
Please note that this adapter is only compatible with the Classic35 and Classic50 Post Driver models.
