This listing is for ONE 2-7/8" hidden shackle locks keyed alike and two keys. 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. These locks offer Ideal protection against bolt cutter attacks. The extra heavy duty 2-7/8" wide padlocks are 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 two keys with the purchase of this 1 pack. You can order up to eight locks keyed alike. This style lock is also available in a 2-pack, 3-pack and 4-pack. To purchase visit our Amazon Store (click on our logo), or via the Master Lock link under this pages title.
