This handpiece guard is for the six flute scaling. It is slightly larger than the guard for the other heads. It fits the Haskins-Strand and Food Machinery of America scalers only.
This tool is made expressly for scaling fish with very large scales. They are used mainly in Asia for Carp and other large scale fish. These fish are not normally seen in other parts of the world.
It is now made of high strength, impact resistant, glass-filled nylon.
