STURDY KEYED PADLOCKS: Our padlock set includes four 40mm steel padlocks. Each padlock measures 6.4 x 4.2 x 2.4 cm. They come with two keys each, so you have your everyday key and a spare in case of loss. These are suitable for both indoor and outdoor use and are resistant to weathering, rust, heat, and fading. HIGH SECURITY: Each padlock features multiple security features. The padlock body consists of approximately 21 laminated sections held together by eight strong rivets. The shackle is 6mm thick, making it difficult to cut, force, or break. We recommend regularly oiling or greasing the lock for extended performance. A keyed padlock is a good way to deter opportunistic thieves and protect your belongings. SECURITY: The bottom of this unique padlock is reinforced with a plastic cover to prevent scratches. Thanks to this protection, the metal body of the padlock won't rub against or scratch your gate or fence in windy conditions. It also provides additional protection for the lock
