Master Lock Black Combination Padlock 4-Pack - Resettable Security

In this review of the Master Lock Black Combination Padlock 4-pack, the reviewer finds a straightforward, reliable option for those needing keyless security for lockers, gates, and gym storage. The single biggest reason to buy is the ability to set and reset a personal four-digit code, which removes the need to carry keys while still offering a solid, weather resistant body and hardened steel shackle for cut resistance. For people who want simple, reusable combination security in a bulk pack, these locks deliver predictable performance.

Key Features

• Resettable four-digit code: The included combination change tool makes it easy to set a memorable code and change it when needed for ongoing convenience.
• Solid body construction: The 2 in body provides strength and weatherability for indoor and outdoor use on lockers, gates, and sheds.
• Hardened steel shackle: The 5/16 in diameter shackle is hardened for improved resistance to cutting and sawing attempts.
• Compact dimensions: With a 1 in shackle length and 1 in width, the lock fits standard hasps and locker hardware without excessive bulk.
• Four-pack value: The set includes four identical set-your-own combination locks, which suits schools, teams, or multiple storage points.

Who It's For

The Master Lock 178EC4 is aimed at students, gym-goers, facility managers, and homeowners who want a convenient, keyless option for securing lockers, gates, or storage areas without spending on high-end security hardware. The resettable code and four-pack format make it practical for organizations that need multiple identical locks.

Those who require maximum tamper resistance or heavy industrial security should consider hardened specialty locks with larger shackles or disc mechanisms, as this padlock is a mid-range combination lock focused on convenience and general cut resistance rather than extreme attack protection.
