Introducing BumpStop TECHNOLOGY, the latest solution to the growing threat of lock bumping. Lock bumping, a surprisingly simple method of breaking into locked doors and padlocks, poses a significant risk to personal property security. The majority of locks in use today are highly susceptible to bumping, making it a serious concern for individuals and businesses alike. However, with the innovative BumpStop Advanced Cylinder Technology, this vulnerability is effectively addressed.

The BumpStop Advanced Cylinder Technology utilizes a unique reverse rake tapered driver pin, high-performance springs, and tightly machined cylinder chambers, all of which are encompassed in a patent-pending design. This design prevents the transfer of force from the bump key to the pins during a bump attempt, ultimately blocking the rotation of the cylinder and ensuring that the lock remains securely closed.

For enhanced security, the ProSeries Padlocks are designed for commercial and industrial applications, featuring a solid iron shackle shroud that resists physical attacks and a removable cylinder that can be easily replaced or re-pinned. The locks also incorporate a 5 spool pin tumbler cylinder for increased pick resistance, as well as a dual ball bearing locking mechanism that withstands pulling and prying.

Moreover, the locks are specifically engineered for harsh outdoor conditions with the exclusive Pro Series Weather Tough cover, which shields the lock from water, ice, dirt, and grime. The chrome rustproofing not only provides long-lasting durability but also ensures protection against the elements.

Furthermore, these high-security locks come with a limited lifetime warranty and are available in packs of four, each keyed alike to provide convenience and continuity in security measures. In instances where two 4-packs are ordered, it is essential to note that they may not necessarily be keyed the same. To ensure keyed alike packs, customers must order the 8-pack.

With dimensions of 2-1/2 inches wide and a 7/16-inch diameter hardened boron alloy shackle with 1-1/8 inch inside height clearance, these locks offer robust security in a compact and durable form. The rekeyable 5-pin cylinders with spool pins provide an additional layer of protection against picking attempts, further solidifying the locks' security features.

Equipped with the BumpStop Advanced Cylinder Technology, the ProSeries Padlocks are the ultimate solution for robust security and peace of mind.
