Frequently Asked Questions

Q: Can this flip door lock be installed on both wooden and metal doors?

A: Yes! The zinc alloy flip door latch can be mounted on a wide variety of door materials including wood, metal, and composite surfaces. As long as you can screw into the door frame or wall surface, it will work effectively.

Q: What is the difference between the 90° and 180° mounting options?

A: The 90° mounting angle positions the latch perpendicular to the door frame — ideal for narrow spaces where the door sits flush against a wall. The 180° option mounts the latch flat along the door surface, great for sliding barn doors or larger gate applications. Both configurations offer strong anti-theft security.

Q: Is this barn door latch suitable for outdoor use?

A: Yes. The multi-layer corrosion-resistant coating on the zinc alloy body makes this door bolt suitable for outdoor environments such as garden gates, sheds, and balcony doors where exposure to moisture is a concern.

Q: Do the installation screws come included with the door bolt?

A: Yes, the package includes all the screws you need to install the flip door latch straight out of the box — no separate hardware purchases required.
