These like the ones I posted above are basically the same. I put them on the bottom side of the rim and then clamp the claws on the protectors. Mine only has three clamps so I use three. Yours probably has four claws so you would need four. I have a manual machine but have used mine on an air/electric machine too.
I apologize if I don't understand how your machine works.
I have no idea what SupraSabre is doing to them I've had the same ones for years and they are tough as nails.
Clamp from my old Coats 220
