Master Lock High Security Padlocks with BumpStop Technology

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 four (4) High Security Keyed Alike Padlocks with 8 keys. ProSeries Padlocks are designed for Commercial/Industrial applications and come with a Limited Lifetime Warranty. These locks feature the BumpStop Advanced Cylinder Technology, which offers enhanced security against the threat of lock bumping.

Ideal for harsh outdoor conditions, the exclusive Pro Series Weather Tough cover protects the lock from water, ice, dirt, and grime. The solid iron shackle shroud resists harsh physical attacks, and the removable cylinder can be replaced or re-pinned. The 5-spool pin tumbler cylinder provides added pick resistance, while the dual ball-bearing locking mechanism resists pulling and prying.

It is important to note that if you order two 4-packs or any multiple of four, they may not necessarily be keyed the same. The dimensions of these padlocks are as follows: a 2-1/8 wide heavy steel body with a 5/16 diameter hardened boron alloy shackle and a 1-3/16 inside height clearance.

In summary, these High Security Keyed Alike Padlocks with BumpStop Advanced Cylinder Technology offer superior protection against the growing threat of lock bumping, while also being designed to withstand harsh outdoor conditions and resist various physical attacks. The Limited Lifetime Warranty and the removable, re-pinnable cylinder add to the overall value and versatility of these security products.
