The Bulkhead Adapter allows you to drive vinyl sheet pilings for building bulkheads or seawalls.  The unit features adjustable fingers that allow you to control the spacing based on the thickness of the material you are driving.  By changing how the fingers are mounted, you can create spacings of 0.25", 0.355", and 0.46" which will accommodate all the major thicknesses of vinyl sheet piling.  Simply screw the adapter onto a scrap 4x4 and you're ready to start driving vinyl or metal pilings.
