combination wire lock|TSA Approved Luggage Locks for Secure Travel & Gym Use

A combination wire lock is a flexible, portable security device with a braided steel cable and combination mechanism, ideal for securing luggage, bikes, bags, or even small storage lockers. As a versatile core product of Shanghai Kuntu Industrial Co., Ltd.—a BSCI-certified manufacturer with over 20 years of experience in designing and producing portable security solutions—this lock is engineered to strike a perfect balance between flexibility, long-term durability, and key-free convenience. It caters to a global audience, including frequent travelers, daily commuters, cyclists, students, and small business owners who need reliable security without the hassle of managing physical keys. Practical application scenarios highlight its adaptability across different regions and needs. For a frequent business traveler based in the United States who flies 15+ times annually, Kuntu’s combination wire lock is a travel essential: the 6mm-thick braided steel cable (composed of 12 individual steel strands woven together) easily loops through the zipper pulls of a checked suitcase, and the 3-digit mechanical combination (with 1,000 possible combinations) is simple to remember yet hard for unauthorized users to guess. Critically, the lock is TSA-approved—equipped with a special slot that allows TSA agents to use a master key for inspection, avoiding the risk of the lock being cut or the suitcase damaged. After two years of use, the traveler notes that the cable shows no signs of fraying, and the combination dial still turns smoothly, even after exposure to airport baggage handling, rain, and humidity. A daily cyclist in Vancouver, Canada, relies on the 1.2m-long version of this lock to secure their commuter bike to public racks outside offices and cafes. The cable’s hardened steel construction resists cuts from basic tools like wire snips, and its flexibility lets the cyclist loop it through both the bike’s frame and rear wheel—preventing theft of individual components. The cyclist appreciates not having to carry a key, especially during rainy commutes when pockets are full of gear. For a university student in Melbourne, Australia, the compact 15cm×3cm×2cm lock fits easily in a backpack pocket, securing a gym bag in shared locker rooms. The cable loops through the bag’s handles and the locker’s metal bar, and the combination can be reset in 30 seconds if the student suspects someone has learned it—providing peace of mind for storing laptops, textbooks, and sports equipment. Kuntu’s combination wire lock stands out for its thoughtful design and quality materials. The lock body is crafted from high-grade zinc alloy, treated with a nickel-plated finish that resists corrosion and scratches—ensuring it remains functional even after years of outdoor use or exposure to moisture. The braided steel cable is coated with a PVC layer, which not only protects the surfaces of luggage, bikes, or lockers from scratches but also enhances grip, making it easier to handle. Two versions are available: mechanical (with a rotating dial) and digital (with a backlit keypad). The mechanical version requires no batteries, making it ideal for long-term storage or travel where power access is limited, while the digital version’s backlit keypad is perfect for low-light environments like hotel rooms or night-time bike storage. Cable diameters range from 4mm (for lightweight items like backpacks) to 8mm (for heavy-duty use like securing bikes or large storage containers). All models meet international security standards, including TSA requirements for travel and EN 1300 for general lock durability. For clients with specific needs—such as custom cable lengths (up to 2m) for securing large items, or branded color options (black, blue, red) to match corporate or retail aesthetics—Kuntu’s R&D team can provide tailored solutions, supported by the foreign trade team’s expertise in navigating global shipping and compliance. As pricing varies based on cable diameter, length, and whether the lock is mechanical or digital, we encourage you to contact our foreign trade team for a personalized quote, along with samples to test durability and functionality.
