1. Drill a hole in the narrow edge of the door - at the height where you want to place the door handle. The hole will be used for the latch that keeps the door closed.

2. Position and hold the latch over the hole in the door. You should be able to see the hole through the latch plate as you line up the door.

3. Use a pencil to trace around the latch plate on the door.

4. Remove the latch plate, then use a hammer and chisel to remove the wood in the marked area. Ensure the depth is equal to the thickness of the latch plate. Once complete, the board should be flush with the edge of the door.

5. Use a drill bit to drill the hole where the door handle will be placed. Drill all the way through to the other side of the door.

6. Reposition the latch plate and mark the two screw holes with a pencil. Drill pilot holes and insert the latch, then screw in the latch plate.

7. Door handles have two halves, usually joined together with two long screws. Insert the door handle into both sides of the door, making sure to line up the screw holes with the centre locking mechanism latches, which should fit the inside door handle

8. Finally, attach the door panel to the door frame. Lock the door in place and latch. Use a pencil to trace the front striker plate and chisel out the wood from the door frame. Use a drill bit to create a hole in the centre of the latch entry. Screw in the strike plate, then open and close the door to check that everything is as it should be
