A Taylors Spindle is normally used in situations where one door handle is being fitted,
for example on a cupboard door. In this situation the circular end of the Taylors spindle is
screwed to the door and the door handle is fitted onto the spindle in the usual way.
Because the spindle is screwed to the door, the door handle or knob used will not be
able to rotate. Instead of a latch, a ball catch is normally used and the door is pulled
open and pushed closed.
