Master Lock High Security Pro Series Padlocks with BumpStop Technology

Introducing the innovative BumpStop TECHNOLOGY - Lock bumping, a surprisingly simple method of breaking in through locked doors and padlocks, has become the newest emerging threat to personal property security. Most locks currently in use are highly vulnerable to bumping, but now there's a solution. Our BumpStop Advanced Cylinder Technology features a patent-pending design that includes a unique reverse rake tapered driver pin, high-performance springs, and tightly machined cylinder chambers. This design prevents the transfer of force from the bump key to the pins during a bump attempt, effectively blocking rotation of the cylinder to keep the lock securely closed.

In this listing, you will receive four (4) High-Security Keyed Alike Padlocks with 8 keys. These ProSeries Padlocks are specifically designed for Commercial/Industrial applications and come with a Limited Lifetime Warranty. Please note that if you order two 4-packs, they may not necessarily be keyed alike. To guarantee that you receive two 4-packs keyed alike, you must order the 8-pack.

These padlocks are perfect for harsh outdoor conditions with their exclusive Pro Series Weather Tough cover that protects the lock from water, ice, dirt, and grime. The solid iron shackle shroud provides resistance against physical attacks, and the removable cylinder can easily be replaced or re-pinned. The 5 spool pin tumbler cylinder adds extra pick resistance, while the dual ball bearing locking mechanism is designed to resist pulling and prying.

The dimensions of these padlocks include a 2-1/8" (54mm) wide heavy steel body, each weighing 1.55 lbs, and a 5/16" (8mm) diameter hardened boron alloy shackle with 3/4" (19mm) inside height clearance. Additionally, the solid iron shackle shroud and the 5 spool pin tumbler cylinder further enhance the security features of these padlocks. Upgrade your security with our BumpStop Advanced Cylinder Technology padlocks today.
