Versatile security for school, gym, and gate use

The Master Lock 178EC4 offers a confident, durable feel with a 2-inch-wide solid body and a hardened steel shackle. Its sleek black finish and compact silhouette convey reliability in everyday scenarios, while the four-digit dial opens up thousands of possible combinations. The combination is resettable, giving you flexibility to tailor access without carrying keys. A practical choice for spaces that see frequent handling, from lockers to gates.

Set your own four-digit code with ease using the included change tool. The dial delivers smooth rotation and clear feedback as you lock in a new combination, making recall straightforward for authorized users. The 0-0-0-0 preset offers a simple starting point, helping you begin right away, while the broad range of combinations reduces the chance of predictable codes. This feature is especially helpful for households, classrooms, and teams where multiple people need dependable access without sharing keys.

Designed for both indoor and outdoor environments, the 178EC4 is built to withstand everyday weather and handling. The solid body and hardened shackle resist common wear and cutting attempts, providing a sense of lasting value in shared spaces. When you buy the 4-pack, you gain flexible security options—whether you want to secure individual lockers, gates, storage cabinets, or back-of-house doors, you can assign different codes to different access points without duplicating keys.

Master Lock backs the 178EC4 with a Limited Lifetime Warranty, reinforcing confidence in a trusted brand. While no one can guarantee a specific outcome, this set offers a practical, user-friendly solution for managing access in busy environments. If you’re looking for a straightforward, reusable padlock system that balances simplicity with durable performance, the 178EC4 set is worth considering for multiple locations and use cases.
