【Enhanced Security】This re-codable combination lock adds a 4-digit combination to ordinary door latches, allowing you to set up to 10,000 possible passwords, significantly enhancing your security and privacy. The default password is 0-0-0-0; no key needed, no worries about loss. 【Strong and Durable】This padlock is made of high-quality zinc alloy, with a 10mm diameter solid steel bolt and covered with a waterproof coating. It protects the padlock from rust and weather, improves its wear resistance, hardness, and ensures its resistance to picking and durability. The handle is also made of solid steel, resistant to breakage and loosening. 【2 Installation Methods】Our combination slide bolt lock supports two installation methods: vertical and horizontal. The slide bolt lock kit comes with a cover for horizontal use and a metal side door buckle for vertical use. (Note: The bolt must be aligned with the lock cover or side door buckle.) 【Easy to Install】Comes with 6 tamper-proof screws, the slide bolt lock is used with an electric screwdriver and drill to mount it on your door frame and tighten the screws after aligning with the lock cover. Installation takes only a few minutes, simple and quick. (Note: One-way screws cannot be removed once installed, and the installation position must be confirmed before installation!) 【Suitable for Indoor and Outdoor Use】. With a size of 120 x 45 x 25 mm, the combination lock is easy to install and fits into the most compact spaces. The combination lock is perfect for versatile use, including school or home lockers, garden sheds, cabinets, storage spaces, garden gates, farmhouses, wardrobes, wine cellars, and any place where you want to maintain security and privacy.
