Master Lock Magnum Padlocks - 2 Shackle, Eight Keyed Alike Locks #M5NKALFSTS-8

Introducing the BumpStop TECHNOLOGY - Lock bumping, a surprisingly simple method of breaking through locked doors and padlocks, is unquestionably the newest emerging threat to personal property security. Virtually all locks currently in use are highly susceptible to bumping. However, BumpStop Advanced Cylinder Technology is changing that narrative.

This innovative technology features a patent-pending design that incorporates a unique reverse rake tapered driver pin, high-performance springs, and tightly machined cylinder chambers. In the event of a bump attempt, this design effectively prevents the transfer of force from the bump key to the pins, thus thwarting rotation of the cylinder and keeping the lock securely locked.

When you order, you will receive eight locks keyed alike with a total of 16 keys. For those interested, a longer 2-1/2" (64mm) shackle version is also available by searching for M5NKALJSTS. These locks are equipped with the BumpStop Advanced Cylinder Technology, ensuring maximum security.

Please note that if you order two 8-packs or multiples of this lock, they will not automatically be keyed the same. To have 16 keyed alike, you must order directly from the seller LocksChocksTiedowns, also available on Amazon.

Specifications include a 2" (51mm) wide laminated steel body for superior durability, and a 1-1/2"L (38mm) x 3/8" thick octagonal BORON CARBIDE shackle, which is 50% harder than hardened steel.

The COMMERCIAL MAGNUM series offers unmatched weatherability and security for outdoor, corrosive, and caustic environments. With a stainless steel body cover, top and bottom plates, and a chrome-plated shackle, these locks provide exceptional weather protection and rust resistance. Additionally, the dual-ball bearing locking mechanism ensures superior pry resistance.
