Internal diameter of 131x81mm. This adapter is suitable for driving 5×3″ rectangle posts, or 5" half rounds.
To drive in 5×3″ posts, a pilot hole must be made in the ground first. A 2″ pilot hole is the recommended size. If the ground is very hard or dry, fill the pilot hole with water and leave to soak before driving the posts into the ground.
Our Pilot Core Tool can be used to make a pilot hole, or alternatively an Earth Auger.
