The Master Lock Magnum Laminated Padlock features a laminated steel body for maximum strength and reliability and is surrounded by stainless steel and zinc outer components for weather resistance.

The octagonal-shaped shackle is not only near impossible to grip with bolt cutters but is made of Tough-Cut boron-carbide, 50% harder than hardened steel, offering maximum resistance to cutting and sawing.

The 4-pin cylinders prevent picking and the dual locking ball bearings provide maximum resistance against prying and hammering – requiring both sides of the shackle to be cut to open. The Limited Warranty provides peace of mind from a brand you can trust.
