Master Lock High Security Pro Series 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.

These locks feature the BumpStop Advanced Cylinder Technology. 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.

The padlocks are designed for commercial and industrial applications and come with a limited lifetime warranty. This listing is for four (4) High Security Keyed Alike Padlocks with 8 keys. If you order two 4-packs, they will not necessarily be keyed the same. To ensure you get two 4-packs keyed alike, you must order the 8-pack.

The padlocks measure 2-1/8 (54mm) wide with a heavy steel body, each weighing 1.55 lbs. The 5/16 (8mm) diameter hardened boron alloy shackle has a 3/4 (19mm) inside height clearance.

Please inquire, and we can normally have the padlocks delivered in a couple of days. The BumpStop Advanced Cylinder Technology provides a robust solution to the emerging threat of lock bumping, ensuring the security of your personal property.
