2 HIGH-QUALITY LOCKS: These padlocks have been designed to fit most lock sizes. The long lock measures 16cm (6 inches) in length and 6cm (2.36 inches) in width. When locked, the gap in the shackle measures 13 x 4.8cm (5.11 x 1.89 inches) and the shackle thickness is 7mm. Please refer to the images for full dimensions of these locks. NO NEED TO CARRY KEYS: As these are combination locks, there is no need to carry keys. To create your code, remove the loop on the lock and ensure all dots are aligned with the indicator. Turn the covered end of the lock away from you and pull off the rings. Slide the rings back on with your code and replace the cover. The set comes with full instructions and you can also watch the video in the listing for help. STRONG AND WEATHERPROOF: These combination locks are made from zinc alloy metal. They are a strong material and a strong design that will keep your door, gate, container or locker safe from anyone trying to rob you. With the 4-digit combination, this not only offers keyless convenience, you can feel safe in the knowledge that you can set up to 10,000 combinations per lock. This makes each lock 10 times safer than a 3-digit combination lock. SUITABLE AND SECURE: These locks can be used to lock and secure almost anything. With the long shackle, this is perfect to use with your bike outdoors and can go through the bike's frame and through the wheel for ultimate security. Also great to use with your shed and even for some storage containers.
