Fence Post Hole Digger Vacuum Tube Extensions

A result of engineering excellence, the Fence Post Hole Digger Vacuum Tube Extensions come in different lengths.  Because of this, it is easy to change the length of any of the Holey-Moley Post Hole Diggers, Core Diggers, EZ Reamers and Large Diameter Reamers.  In addition, four lengths are currently available.

As a result of customer input, we offer for options,  14-inches, 28-inches, 36-inches, and 48-inches.  The operational physics of the Holey Moley Digger creates high air velocities in the digger heads. Because of this, the tubes are made for smooth high velocity airflow. Consequently holes as deep as 20 feet have been dug.

Extension tubes are easy to insert between the digger head and the handle assembly.  Steel 5/16-28 bolts secure tube connections together.

Using the Fence Post Hole Digger Vacuum Tube Extension

The male end of the vacuum tube easily slides into the corresponding female section.  The result, is a 2.5-inch very strong joint. Also, each section is easy to secure with two 5/16-28 bolts.  Due to steel construction, the extension tubes are strong enough to meet digging torque requirements.

Because, extensions can be added, depths from 8 to 20 feet are easy to achieve . The vacuum tube extensions are simple to assemble. Therefore, lengths of 20 feet or more are practical.  As a result of different available lengths, the customer can keepi the digger handles between 2 feet and 5 feet off the ground. Therefore, the digger handle is always at a comfortable operating height.
