The Master Lock Commercial Magnum Laminated Steel Padlock with Stainless Steel Body Cover features a 1-3/4in (44mm) wide laminated steel body encased in a stainless steel body cover for maximum strength and weatherability. The 5/16in (8mm) diameter octagonal shackle is 1-1/2in (38mm) long and made of chrome-plated boron carbide, 50% harder than hardened steel, offering maximum resistance to cutting and sawing.
