You'll need this 3-1/2-Inch Doorknob Spindle for our period-style doorknobs. The 9/32in. threaded spindle is suitable for wood doors with a standard thickness of 1-3/8in. to 1-1/2in.

Beyond sharing an appreciation for the beauty of antique doorknob designs, our goal is to help you get what works for you, which is why we sell hard-to-find door hardware parts singly.

  • Steel with Zinc Plating
  • Imported

Tips: This spindle fits our reproduction (and some old) mortise locks and tube latches. It does not fit modern locksets. Contact us with questions. For more door hardware parts, look in Locks & Parts. If you need several parts, you may want to consider a full Interior or Exterior Door Set.
