Our casing adapters are made to withstand the extreme thrust forces of our auger boring machines. Our unique design provides durability by putting the back plate of the adapter in column load with the product casing. We start with a robust back plating that fits directly into the overcut band of our ABM’s master pusher. Atop this plate we mount a 5/8″ x 3″ ring, which is rolled to the diameter of the product casing, then we place many thick gussets around the ring and finish it with a top plate. The design produces an I-Beam effect that holds up to our ABM’s continuous duty rating.
