HEAVY DUTY LOCKS: Included in our set are 3 combination padlocks. Each padlock is 80*40*13mm. Our padlocks open and lock with a number combination, perfect for occasions where you are unable to carry a key. They can be used both indoors and outdoors and are weather, rust, heat and tarnish-proof. HIGH SECURITY: Each lock features multiple safety features. The body of the lock is made of a heavy zinc alloy. The shackle is 6mm thick and this makes them difficult to snip, pry or break. We recommend oiling or greasing the lock regularly to keep it working for longer. The numbers are embossed so are easy and quick to read. They have a textured surface so they are easy to turn. Having the lock on show on your personal possessions, they are a great deterrent to opportunist thieves. EASY TO SET UP: The locks will come with the code 0000 as default. You can change the code by twisting the shackle 90 degrees anti-clockwise. Hold the shackle down and twist the numbers to select your new passcode. The numbers need to line up with the arrow on the side. You can then turn the shackle to its original position and your code will be saved. Make sure you remember your new number code. MULTIPURPOSE: These small locks can be used for so many different purposes. Use them for locking property with high value items such as a shed, garage, workshop, suitcases/baggage/luggage, gym and school lockers, storage boxes and containers, tool boxes and tool stores. Use them around the home on chains, gates, garden fences and sliding doors. They can also be used to secure dog kennels, trailers, bikes or for lock sports.
