This machined back plate is designed to mount onto our 20" 3 jaw or 4 jaw self centering lathe chuck (p/n 202-5449). The mounting holes to mount the back plate to the chuck are drilled and tapped, and the registration (shoulder) needs to be slightly turn down to match the recess on the back of the lathe chuck.

  • Made from high grade cast iron
  • Fits most 20" self centering plain back chuck (please verify the bolt circle diameter and shoulder diameter on the back of the lathe chuck)
  • The back plate may come with two or three additional screws (depending on type) for removal the back plate from the chuck. They are not used to mount the chuck to the back plate, mounting screws should be included with the chuck

What’s Included

  • 6 pcs of studs for mounting into the cam lock on lathe spindle
