Each pack includes four keyed alike locks with two matching keys — both keys open all locks for convenient access. Ideal for securing lockers, sheds, fences, or other equipment.

Usage

These padlocks are best suited for residential and commercial applications where security is needed outdoors — such as school locker rooms, garage sheds, tool storage areas, or fence gates. They’re also suitable for indoor use in offices or gyms. The keyed alike design allows multiple users to share access without needing separate keys. Users should measure their door’s backset, cross bore, and thickness before installation to ensure proper fit.
