How do you install a new door knob?

Install First new knob

  • Examine the two new knobs and then the knob with an extending rod needs to be chosen, which will interlock the latch with the other. This is the important key point to install door knob.
  • Slide the rod into the latch while holding this new knob in place over the hole in the door.
  • Ensure that the knob is centred over the hole before threading and tightening the screws.

Tighten the Latch

  • The latch mechanism is locked in place by threading the latch plate screws down.
  • Use your fingers to push the latch spring in, several times, to test it. The latch will spring back again every time it would be pressed and this will symbolise it is working fine.

Install Second new Knob

  • The first need here is to ensure that the extended rod gets interlocked with the first knob and then you can place the second knob in place.
  • Lock the second knob in place by threading the screws.

Install the Strike Plate

  • The new Striking plate needs to be placed over the latching hole in the door jamb. Then, you need to align it with the hole and any marks that have been left behind by the old strike plate.
