The next stage is to slide the pin to keep the bracket and cylinder together. It will make the door close harder and latch all the way.

Step 5: Watch it Close

Now, open and close your door at least 10 times. If it latches correctly and with speed, you want, 10 times in a row, pat yourself with a big smile.

However, if it does not work correctly, well, prepare yourself to climb up the ladder again.
