Master Lock Commercial Padlocks

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 commercial grade #3 Master Locks are their most commonly sold padlock. This listing is for six 1-9/16" wide padlocks, with BumpStop™ technology, keyed alike (same key unlocks all six), and twelve keys.

This is a set of 6 Keyed Alike padlocks and is ideal for all outdoor applications when needing multiple locks that utilize only one key. The same key opens all locks. Each lock comes with two keys, therefore you will receive a total of twelve keys with the purchase of this 6 pack.
