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

Combination disc lock is a low-profile, keyless security device with a circular disc-shaped body—designed to secure storage units, trailers, gates, sheds, or boat hatches where traditional padlocks’ bulky shape might snag or be vulnerable to prying. Produced by Shanghai Kuntu Industrial Co., Ltd.—a BSCI-certified manufacturer with over 20 years of experience in specialized lock design—this lock is engineered for compact durability, tamper resistance, and ease of use, catering to global clients like storage facility operators, trailer owners, and boaters who need secure, space-efficient locking solutions. Unlike standard padlocks, Kuntu’s combination disc lock’s flat design eliminates leverage points for prying tools, while its combination mechanism removes the risk of lost keys. Real-world applications showcase its unique advantages. A self-storage facility chain in California, USA, uses 2,000 of Kuntu’s combination disc locks to secure client storage units. The lock’s 7cm diameter disc body fits perfectly in the unit’s hasp, with no protruding parts that could be damaged by moving boxes or vandalized. Tenants set their own 4-digit combination, and facility managers use a master reset tool to clear codes when units are vacated—saving 2 hours daily compared to rekeying traditional locks. The lock’s stainless steel body resists rust from California’s coastal humidity, and after 3 years of use, the facility reports a 98% lock functionality rate. A trailer owner in Texas, USA, relies on the lock to secure their utility trailer when transporting equipment. The low-profile design prevents the lock from catching on road debris, and the 6mm hardened steel shackle resists cutting with bolt cutters—critical for securing expensive tools. The owner sets a unique combination for each job, resetting it easily between clients. For a boat owner in Florida, USA, the lock secures the boat’s hatch (storing life jackets and safety gear). The lock’s IP65 water-resistance rating protects it from saltwater spray, and the disc shape fits in the hatch’s narrow hasp—unlike bulkier padlocks that would prevent the hatch from closing fully. Kuntu’s combination disc lock is built for compact security and durability. The disc body is crafted from either 304 stainless steel (for maximum corrosion resistance, ideal for marine or coastal use) or zinc alloy with a powder-coated finish (cost-effective for indoor storage). The combination mechanism is a precision brass 4-digit system, with 10,000 unique combinations—resistant to “code fishing” and jamming from dust or moisture (sealed with a rubber O-ring). The shackle is 6mm-8mm hardened steel (Rockwell hardness 50), with a double-locking design that engages at both ends of the disc body—preventing forced removal. The lock’s low profile (2.5cm thickness) fits in tight hasps, and its smooth edge design eliminates snags. All models meet ANSI/BHMA A156.30 Grade 2 standards for lock durability, with a 10,000-cycle opening/closing test rating. For clients with specific needs—such as longer shackles (for thick trailer hasps), key override options (for emergency access), or custom colors (to match facility branding)—Kuntu’s R&D team can develop tailored solutions. The foreign trade team ensures compliance with regional regulations, including EU RoHS and U.S. ASTM standards.
