Tas lock (commonly referred to as “TSA lock,” aligning with global travel security terminology) is a specialized lock approved by the U.S. Transportation Security Administration (TSA) and compatible with international security agencies (e.g., CATSA in Canada, EASA in the EU)—designed to secure luggage, backpacks, or travel bags while allowing authorized agents to inspect contents without damaging the lock. Manufactured by Shanghai Kuntu Industrial Co., Ltd.—a BSCI-certified company with over 20 years of experience in travel security products—this lock balances convenience for travelers and compliance with airport security protocols, making it essential for anyone traveling by air globally. Kuntu’s tas locks eliminate the risk of locks being cut or luggage damaged during inspections, a common issue with non-approved locks, while providing reliable protection against theft. Real-world applications demonstrate its utility for diverse travelers. For a backpacker in London, UK—who travels across Europe by train and plane—Kuntu’s tas lock secures their backpack (which holds a laptop, passport, and travel documents). The mechanical 3-digit combination version is lightweight (50g) and fits the backpack’s zipper pulls, and the traveler can reset the code in 30 seconds if they share access with a travel companion. During a flight to Barcelona, Spanish security agents inspected the backpack using a TSA master key, and the lock functioned perfectly afterward—no scratches or damage. The backpacker appreciates that the lock’s ABS plastic body is durable yet lightweight, adding no extra bulk to their pack. A corporate travel manager in Chicago, USA, orders Kuntu’s tas locks in bulk for employees who travel frequently. The digital version’s 4-digit code is easy to assign to individual employees, and the low-battery alert ensures locks never fail during trips. The locks are branded with the company logo, reinforcing brand identity, and the TSA approval gives employees peace of mind that their luggage won’t be damaged. For a family in Rio de Janeiro, Brazil, the tas locks secure their beach bags and suitcases during a trip to Florida. The mechanical locks require no batteries, ideal for beach days where sand and water could damage electronics, and the large combination dial is easy for kids to use (with a simple 3-digit code set by parents). Kuntu’s tas lock is engineered with travel-specific durability and compliance in mind. Two core versions are available: mechanical (rotating dial) and digital (keypad). The mechanical model uses a precision brass combination mechanism, resistant to jamming from sand or dust, with 3-digit combinations (1,000 unique options) and a recessed TSA slot that accepts all 7 official TSA master keys—ensuring compatibility with global airport security. The digital model features a backlit keypad for low-light use (e.g., hotel rooms or airport terminals), 4-digit combinations (10,000 options) for added security, and a low-battery LED indicator (powered by a CR2032 battery that lasts up to 18 months). Both versions have a body made of either impact-resistant ABS plastic (lightweight for carry-ons) or zinc alloy (for heavy-duty checked luggage), with a flexible stainless steel shackle that fits most zipper pulls or bag hasps. All tas locks meet TSA’s “Accepted Lock” program standards and are compatible with other global agencies like Canada’s CATSA and Australia’s Qantas security protocols. They also have an IP44 water-resistance rating, protecting against rain or accidental spills during travel. For clients with custom needs—such as branded locks (logo engraving for travel agencies or luggage brands), color matching (to align with product lines), or custom shackle lengths (for oversized bags)—Kuntu’s R&D team delivers tailored solutions.
