This lock is the largest available in Masterlock's Pro Series of high security, weather-tough padlocks.

Designed for use both indoors and outdoors, the 6127 is made from heavy-duty steel for superior long-life use and comes with a Zenex thermoplastic cover which resists the effects of the weather. This cover also includes polymer shackle seals for preventing water seepage and a built-in protective cover for the interior lock further protects the lock's integrity.

The shackle of this lock is made from a hardened boron alloy for maximum resistance against cutting.
