Product Details
The Master Lock® No. M1LJSTS Magnum laminated steel padlock is designed for enhanced security and durability, featuring a 1-3/4 inch (44 mm) wide laminated steel body that is encased in a stainless steel body cover to provide maximum strength and weatherability. Equipped with a 5/16 inch (8 mm) diameter octagonal shackle that is 2-1/2 inches (64 mm) long and made of chrome-plated boron carbide, this padlock is 50% harder than hardened steel, ensuring superior resistance to cutting and sawing. The 4-pin cylinder mechanism is engineered to prevent picking, while the dual locking ball bearings offer maximum resistance against prying and hammering. The Commercial Magnum series is specifically designed for outdoor use, making it ideal for corrosive and caustic environments, thus providing a higher level of security and weatherability.
