Master Lock Magnum
Boron-carbide Construction | Set-your-own Combination
This Magnum padlock has patented octagonal boron-carbide shackles, which are 50% harder than hardened steel, and nearly impossible to cut with bolt cutters.
The chrome plated, zinc die-cast body, and covered keyway allow for superior weather resistance, while the reinforced body bumper prevents against scratching. The increased shackle width and clearance allow for a broader application fit.
This padlock has set your own combination convenience, and also comes with a back-up key.
