10 Best Combination Locks 2025 in the United States

The Puroma Combination Lock 10 Pack offers a practical and secure option for those needing multiple padlocks, especially useful for gym lockers, toolboxes, gates, and storage units. These locks feature a 4-digit combination, which creates 10,000 possible codes—significantly better security than 3-digit alternatives. The combination is resettable, allowing you to personalize your code easily, which adds convenience and flexibility. Made from a high-strength zinc alloy body with a steel shackle, these locks are designed to resist common attacks like sawing and hammering, promising durability. They are also weatherproof, making them suitable for outdoor use without worry about rust or corrosion. The compact and lightweight design makes carrying and handling them straightforward, while the side code window and clear numbers simplify setting and unlocking—even when you’re in a hurry or carrying things.

These locks are best suited for moderate security needs such as lockers and sheds rather than high-security applications. This set provides reliable security and ease of operation at a good value, especially if you need multiple locks at once.

The Puroma 4-digit combination lock is a solid choice for anyone needing a reliable padlock for lockers, gym bags, gates, or toolboxes. It’s made from sturdy alloy steel and zinc, which gives it good durability and resistance to rust, making it suitable for outdoor use thanks to its weatherproof design. The 4-digit code offers 10,000 combinations, providing more security than traditional 3-digit locks, which is great if you want to keep your belongings safer.

One of the lock’s user-friendly features is its side window design. This lets you easily set and enter the combination with one hand, which is convenient compared to locks that require two hands. The lock is also compact and lightweight, so it’s easy to carry around or use in different places.

The materials used suggest it’s strong enough for everyday security needs but may not withstand heavy brute force. The resettable combination feature adds flexibility since you can change your code as needed. This lock is especially fitting for students, gym-goers, or anyone looking for a weather-resistant combination lock that’s straightforward to use. For everyday use, Puroma’s lock offers a good balance of convenience, durability, and security, though heavier-duty options may be preferable for high-risk areas.

The Master Lock Gold Outdoor Combination Lock is designed for serious security needs, making it ideal for gates, sheds, and storage units. Constructed with a robust zinc body and a reinforced bumper, it offers significant strength and reliability. Weather resistance is a standout feature, with a shackle seal and covered dials to protect against the elements, ensuring durability in outdoor settings.

The octagonal boron-carbide shackle is exceptionally tough, being 50% harder than hardened steel, which enhances its resistance to cutting and prying. The lock’s dimensions provide a good balance of size and security, with a 3/8 inch thick shackle that fits a variety of applications. Setting and recalling the four-digit combination is straightforward, and the lock is resettable without needing a tool, adding to its ease of use.

The one-directional dial feature is a helpful addition for low-light conditions. However, the lock's weight, nearly 2 pounds for the pack, might be cumbersome for some users. Also, while the combination mechanism is user-friendly, it may not deter determined thieves as much as a keyed lock might. Available in a pack of two, it offers good value for securing multiple items. This lock is best suited for users who need a durable, weather-resistant padlock for outdoor use, and appreciate the convenience of a resettable combination.
