Designed for inward and outward swinging wood or metal doors, this door latch uses gravity locking to provide high security for animals, babies and plants by preventing predators from entering your yard. This sturdy latch is made of thick steel with matte black powder coating, rust resistant and has a long service life indoors and outdoors. Our wood fence latch features a quick release locking system that works without a cable - just your finger or thumb. The locking bar can be mounted on the left or right. The kit comes with all parts and accessories including 6 black steel screws for easy installation. The 4.7 inch lever has a self-closing feature and is compatible with all types of large and small outdoor gates including wood, metal, wrought iron, vinyl and PVC. Use the self-locking gate opener on any decorative gate in your yard, patio, baby gate, privacy fence or even a chicken coop door. For additional security, it can also be used with a regular padlock (not included).
