Solid construction: zinc alloy padlock body provides corrosion resistance and reliable protection in daily use. Strong, flexible cable: 3 mm diameter, 12-inch steel cable combines strength and flexibility to thread through zippers, handles, and latches while remaining compact and easy to store. 4-digit combination security: 10,000 possible codes—no key needed. Set your own combination and keep it secure; write it down or take a photo to avoid being locked out. Compact and lightweight: small footprint and low weight for easy packing and transportation without adding bulk to your luggage or gear. High load capacity: rated to hold up to 50 kg. Note: wire ropes on many padlocks may fail when subjected to loads over 5 kg, so this model offers higher strength for tougher needs. Wide compatibility: works with luggage and suitcases, backpacks, tool boxes, helmets, weapon cases, and other items that accept a cable-style lock. Practical uses Travel: secure suitcase or backpack zippers when checking or storing baggage. Worksite and storage: lock tool boxes or equipment cases to deter theft on the job. Sports and transport: secure helmets, instrument cases, or weapon cases during transport. Why choose this lock Keyless convenience and a large combination space for better security.
