Combination lock, in its various forms, is a keyless security device that has found wide - spread use in different applications, from securing luggage and lockers to protecting storage units and gates. Shanghai Kuntu Industrial Co., Ltd., a BSCI - certified manufacturer with over 20 years of experience in lock production, offers a comprehensive range of combination locks, catering to diverse customer needs across the globe. For luggage and travel security, Kuntu's combination locks are designed to be lightweight yet durable. A 3 - digit mechanical combination lock, for example, is made of impact - resistant ABS plastic, weighing only 50g, making it an ideal choice for backpackers and frequent flyers. The lock's 3 - digit combination provides 1,000 unique options, and it has a recessed TSA slot, ensuring compatibility with airport security inspections worldwide. A traveler in London, UK, uses this lock to secure their backpack during a multi - country trip. The lock fits the backpack's zipper pulls perfectly, and the traveler can easily reset the code in 30 seconds when sharing the backpack with a travel companion. In the context of locker security, Kuntu's combination locks are engineered for frequent use. A university in Toronto, Canada, uses 5,000 of Kuntu's combination locks for student dorm lockers. The lock's 4mm stainless steel shackle is specifically designed to fit the dorm's narrow 8mm hasp. The mechanical 3 - digit combination requires no batteries, eliminating the problem of dead locks due to drained power. Students can reset their codes in 30 seconds using a simple dial sequence, and the university's facilities team can use a master tool to clear codes between semesters, saving over 100 hours of rekeying time. Kuntu's combination locks come in two main types: mechanical and digital. Mechanical locks use a rotating dial mechanism, often with precision brass components for smooth operation and resistance to jamming. Digital locks feature a keypad, with options for 3 - 4 digit codes (providing 1,000 - 10,000 unique combinations), backlit displays for low - light use, and additional features like auto - lock and lockout functions. The lock bodies are made of materials such as zinc alloy (for durability) or ABS plastic (for lightweight applications), and the shackles are typically made of stainless steel, with thicknesses ranging from 5mm for lighter - duty use to 10mm for heavy - duty outdoor applications. Customization options are available for clients. This includes custom packaging, logo engraving on the lock body or shackle, color matching to brand guidelines, and even modified combination lengths based on the application. Kuntu also offers dedicated account managers for large orders, providing real - time production updates and logistics support. All locks meet international standards, such as ANSI/BHMA and EN 1300, ensuring compliance with regional regulations.
