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.

Buying Guide for the Best Combination Locks

Choosing the right combination lock can be crucial for securing your belongings, whether it's for a locker, a bike, or a storage unit. The key to finding the best combination lock for your needs is to understand the various specifications and how they align with your specific requirements. Here are some key specs to consider when selecting a combination lock and how to navigate them.
MaterialThe material of a combination lock is important because it determines the lock's durability and resistance to tampering. Common materials include hardened steel, brass, and aluminum. Hardened steel is the most durable and resistant to cutting or breaking, making it ideal for high-security needs. Brass offers good corrosion resistance, which is useful for outdoor use. Aluminum is lightweight and suitable for less critical applications. Choose a material based on where and how you plan to use the lock.
Shackle ThicknessThe shackle is the U-shaped part of the lock that secures it to an object. Shackle thickness is a key factor in the lock's security. Thicker shackles are harder to cut or break, providing better security. Shackles typically range from 5mm to 10mm in thickness. For high-security needs, such as securing a bike or a storage unit, opt for a thicker shackle. For less critical applications, like a school locker, a thinner shackle may suffice.
Combination LengthCombination length refers to the number of digits in the lock's combination code. Longer combinations offer more security because they are harder to guess. Common lengths include 3-digit, 4-digit, and 5-digit combinations. A 3-digit combination provides 1,000 possible combinations, while a 4-digit combination offers 10,000 possibilities, and a 5-digit combination provides 100,000. For high-security needs, choose a lock with a longer combination. For everyday use, a 3-digit or 4-digit combination may be sufficient.
Resettable CombinationA resettable combination allows you to change the lock's code as needed. This feature is important for maintaining security, especially if you suspect someone has learned your combination. Locks with resettable combinations are convenient for shared use or if you frequently change the items you are securing. If you need flexibility and enhanced security, opt for a lock with a resettable combination.
Weather ResistanceWeather resistance is crucial if you plan to use the lock outdoors. A weather-resistant lock can withstand exposure to rain, snow, and extreme temperatures without rusting or malfunctioning. Look for locks labeled as weather-resistant or those made from materials like stainless steel or brass, which are less prone to corrosion. If you need a lock for outdoor use, prioritize weather resistance to ensure longevity and reliability.
Ease of UseEase of use refers to how simple it is to operate the lock. Some combination locks have larger dials or ergonomic designs that make them easier to handle, especially for individuals with limited dexterity. Consider who will be using the lock and how often it will be used. If ease of use is a priority, look for locks with user-friendly features like large, easy-to-turn dials or clear numbering.
