Simplified Master Lock High Security Pro Series Keyed Alike Padlocks

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.

Inquire, and we can normally have them in a couple of days. Four (4) High Security Locks Keyed Alike with 8 Keys. ProSeries hardened solid steel body padlocks are designed for Commercial/Industrial applications. These locks feature the BumpStop Advanced Cylinder Technology (for explanation, see more product details below). The same lock with a shorter shackle is also available; search 6230NKA.

ATTENTION: 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.

APPLICATIONS: These locks are popular for use in industrial and manufacturing environments, as well as by business owners to secure their storefronts and business gates. In marine recreation, they will withstand the harsh elements. They are also used for utility meters, substations, and cable boxes, among other applications.

DIMENSIONS: The locks are 2-1/2" (64mm) wide, with a round solid steel body, each weighing 1.68 lbs. They have a 7/16" (11mm) diameter hardened boron alloy shackle with 2" (51 mm) inside height clearance.

The CHROME rustproofing provides longer life. These high-security, rekeyable 5-pin cylinders with spool pins are virtually impossible to pick. Additionally, a dual ball bearing locking mechanism resists pulling and prying.
