Product Description

The $76.95 special price is for THREE 2-7/8" hidden shackle locks keyed alike (same key unlocks all three) and six keys. Individually these locks cost $27.75 each. Therefore a savings of $6.30. 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 six (6) keys with the purchase of this 3 pack. You can order up to eight locks keyed alike. This style lock is also available in a 2-pack and a 4-pack. To purchase visit our Amazon Store (click on our logo), or via the Master Lock link under this pages title. To reach any desired quantity order a combination of 2-packs, 3-packs, or 4-packs. 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.

By Ken on April 9, 2012
I bought the 3 pack for my enclosed trailer which has a side door. The keyed alike feature makes it very convenient to open any lock without searching for the right key. These locks are very secure, very durable and they wont "bounce" open while going down the bumpy roads of the nation. I replaced open schackled locks with the puck design because someone cut my previous locks off. The first set of puck locks I bought did not have the "bump" technology and they eventually fell off one by one. Since I purchased this set of Bump Locks, they have never fallen off in transit. They are exposed to the elements and have never failed in trying to open or close them. These locks provide me with peace of mind in knowing that the contents of my trailer are secure!
