Introducing the ideal padlock for truck drivers. This padlock features a 2.5-inch (65mm) nickel-plated hardened steel double locking shackle to make sure your cargo or storage bin is secure. With a heavy-duty solid steel design and a corrosion-resistant brass cylinder it is built to withstand tough conditions on the road. Plus we provide you with the convenience of three keys offering redundancy and backup so you are always in control. Over time dust particles and chemicals in the air may settle in the lock. This may create friction inside the components and impede the performance of the lock. Regular cleaning and lubrication every 3-6 months is recommended to keep your locks operating like new
