.FEATURING BumpStop TECHNOLOGY - Lock bumping a surprisingly simple method of breaking in through locked doors and padlocks - is undoubtedly the newest emerging threat to personal property security. And virtually all locks in use today are particularly vulnerable to bumping. Until now...

BumpStop Advanced Cylinder Technology employs an innovative, patent pending design which utilizes a unique reverse rake tapered driver pin, high performance springs and tightly machined cylinder chambers. During a bump attempt, this design prevents the transfer of force from the bump key to the pins and therefore blocks rotation of the cylinder so that the lock remains locked.

This listing is for two (2) 2-7/8" wide hidden shackle locks keyed alike (same key unlocks all) and four keys. With rekeyable six-pin tumbler cylinders and tens of thousands of key changes, these padlocks offer maximum protection against drilling, sawing, prying, crowbars, dent pullers and hammers — so they’re ideal for protecting high security areas and are adaptable for applications on garages, storage buildings, vehicles, commercial buildings, industrial plants and vending machines. The Lock body conceals the shackle, defeating attempts to pry and cut. Ideal for transportation, vending & industrial applications.
