Master Lock Company's new-generation ProSeries Resettable Combination Padlocks feature an exclusive octagonal shackle, which offers less surface for a would-be intruder’s bolt cutter. In lieu of hardened steel used in standard locks, these shackles are made of enhanced boron-carbide alloy. Together, the shackle design and two alloy make these locks twice as hard to cut, the company said. In addition to durable brass, stainless steel and die cast bodies, exclusive Master Lock shackle seals and dial covers shrug off weather while keeping dust and dirt away from internal mechanisms to provide extended, trouble-free lock operation, Master Lock said. The ProSeries' large ergonomic dials also enable operation with gloves, in low light or even total darkness.
