Padlocks come in a variety of colors for lockout identification compliance. Choose these locks if you need several locks that open with the same key. If the lock or key with the key number you want isn’t listed, order the “Other Key Numbers” and specify your desired key number.
Aluminum-body locks are more corrosion resistant than steel-body locks, but are not as strong.
Pin-tumbler key locking mechanisms are the most difficult locking mechanisms to pick. When choosing between padlocks with four or five pins, the lock with five pins is harder to pick.

Weather-Resistant Keyed Alike Padlocks



Padlocks have a brass body for excellent corrosion resistance. Choose these locks if you need several locks that open with the same key. If the lock or key with the key number you want isn’t listed, order the "Other Key Numbers" and specify your desired key number.
Hardened steel shackles are stronger than steel and stainless steel shackles. Brass shackles are more corrosion resistant than steel shackles, but are not as strong.
Pin-tumbler key locking mechanisms are the most difficult locking mechanisms to pick. When choosing between padlocks with four or five pins, the lock with five pins is harder to pick.
