The Master Lock Commercial Magnum® No. M5KALFSTS Laminated Steel Padlock with Stainless Steel Body Cover, Keyed Alike - multiple locks open with the same key - features a 2in (51mm) wide laminated steel body encased in a stainless steel body cover for maximum strength and weatherability. The 3/8in (10mm) 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. The 4-pin cylinder prevents picking and the dual locking ball bearings provide maximum resistance against prying and hammering. Commercial Magnum offers a higher level of weatherability and security for applications in outdoor, corrosive and caustic environments.
