You can also measure the height of the other door handles in your house and use this measurement when marking the handles.

All door handle templates are different, so follow the directions that come with your kit for the best results.

Securing the door is a very important step, as it will allow you to drill necessary holes without damaging anything.

These preliminary holes will make it easier to drill in screws later on.

The spindle holes are where the door handle will eventually be inserted.

The narrow part of the door is more difficult to drill into, as it has a smaller surface area. Take extra care when drilling this hole.

If the faceplate does not fit flush with the narrow part of the door, make adjustments with your chisel until it does. Faceplates come in different depths, so it is important to follow your kit’s instructions when chiselling the narrow part of the door.

If the door knobs are not working, unscrew them and double check that they have been fit into the spindle.

Striker plates are mechanisms that keep your door closed.
