Why does Adjust Tru want you to use there backing plate is it just to sell more or is there a real reason. :confused:

Sometimes other brands don't fit their chucks and vise versa.

The Adjust Tru back plate has an extended boss on the chuck side for the adjusting screws to bear against. It is how the adjusting feature work.

You don't have to use it, buy a bison generic plate and turn it down then locate and tap all the holes. Unless time is cheaper than money the adjust tru back plate is not too bad in price.
