Sliding doors often have weak latches. Three simple additions make them much harder to force.
Step-by-step guide
- Add a bar in the track Cut a wooden dowel or fit an adjustable security bar in the bottom track so the door cannot slide.
- Stop the door being lifted Drive two screws partway into the upper track so the panel cannot be lifted out, while still sliding freely.
- Fit a secondary lock Add a keyed or foot-operated sliding door lock at the top or bottom.
- Check the latch Make sure the factory latch actually hooks the keeper. Adjust the keeper if it does not.
- Keep it usable in an emergency Whatever you add, everyone in the home should be able to open it quickly from inside.
