This unit is build using stainless steel and bolts right onto the shredder assembly.
There are two options for this unit; assembled and pieces. The "pieces" unit will include all blades, spacers, axle, and bearings packaged together for you to be assembled. The "assembled" unit will be completely bolted and welded together shipped as a single unit.
