These extra heavy duty 2-7/8" wide ProSeries® Padlocks are designed for Commercial/Industrial applications. The Lock body conceals the shackle, defeating attempts to pry and cut. Ideal for transportation, vending & industrial applications, the high security, rekeyable 6-pin cylinder with spool pins is virtually impossible to pick. Each lock comes with two keys, therefore you will receive a total of eight (8) keys with the purchase of this 4 pack. You can order up to eight locks keyed alike. This style lock is also available in a 3-pack and a 4-pack, search 6271NKA. FEATURING BUMP STOP 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. BumpStopTM 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.
