Internal diameter of 84mm. This adapter is suitable for driving posts between 76mm - 82mm diameter. Adapters are needed to guide your machine & give the best accuracy and efficiency when driving posts. A snug fit is recommended, no greater than 10mm larger than your post. All adapters are interchangeable, except for the Marquee Kit.
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.
