1 3/4" (44mm) Wide Magnum Laminated Steel Padlock w/ 2" shackle

The Master Lock Magnum® No. M1X Laminated Padlocks feature a 1-3/4in (44mm) wide laminated steel body for maximum strength and reliability, and is surrounded by stainless steel and zinc outer components for weather resistance. The 5/16in (8mm) diameter octagonal shackle is made of Tough-Cut™ 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.
