Cap Lock—Cap locks are made from a solid block of iron and cover the entire pin, so they are hard to twist or pry off. Their locking bolt slides into place like a drawer, butting up against the kingpin to secure it. To make them tough to pick, the lock itself is recessed and uses rotating discs—like tumblers in a safe—instead of traditional springs and pins.

Keyed Differently—Choose keyed differently locks if you need locks that each open with a different key.

Keyed Alike—Choose keyed alike locks if you need several locks that open with the same key.
