Retractable Passage Door Locks; White; Top & Bottom Pair; Slide Bolt Action;

The door locks stopped my screen from retracting on windy days. Very easy to install, I did it myself.

I don't need a video of the screen not yet installed showing how to put this on. I need to know how to install this lock and see a video if the screen door is already up!!! Don't waste your money if it can't be installed and your door is already up and installed in your opening. Still waiting on how to install it.
