Tired of losing keys? This ZHEGE combination lock is the answer. It's a 4-digit lock, which means there are 10,000 possible combinations – making it much more secure than a basic 3-digit lock. The best part is you can set and reset your own secret code whenever you want, following the simple instructions. It has a long 2.6-inch shackle (the U-shaped metal part), which is super handy because it can fit through larger hasps on gates, toolboxes, or chain-link fences that a small shackle can't. The lock body is made from a tough zinc alloy, and the shackle is hardened steel, making it resistant to cutting, sawing, and weather. It's also waterproof, so you can confidently use it outdoors on a shed or gate. It features a side window to read the numbers easily, and the dials have a nice click so you know you're on the right digit. It's perfect for securing your gym or school locker, toolbox, storage cabinet, gate, or shed. The package includes two locks. Just remember not to forget your code! The seller offers a 12-month warranty and great customer service. It's a reliable, key-free solution for all your locking needs.
