What is the Best All-Purpose Weatherproof Padlock?

The Abus Eterna Laminated 41 Series is a robust, all-purpose weatherproof padlock suitable for both outdoor and indoor environments. Available in multiple body sizes, this range provides flexibility across a wide variety of applications, from garden gates and sheds to toolboxes, storage units, garages and site equipment.

Keyed Alike and Master Key Options

The 41 Series can be supplied as standard off-the-shelf or made to order in keyed alike or master keyed systems. A major advantage of this range is the ability to match key codes across different sizes. This allows you to select the correct padlock size for each job while still operating all locks with the same key. This is particularly useful for multi-site access, work teams, and situations where key management needs to remain simple.

Why the Abus Eterna Laminated Padlock Performs Outdoors

Outdoor padlocks must withstand rain, frost, dirt, and temperature changes. Many weatherproof padlocks are made from stainless steel to resist corrosion, but stainless steel can be softer and easier to cut. The Abus Eterna laminated series solves this by using hardened steel plates that are individually treated with the Eterna coating before assembly. This provides both weather resistance and strength.

Superior Construction

Unlike lower-cost laminated padlocks, where the galvanising is applied after construction, Abus treats each steel plate before building the lock. This results in far greater protection. Abus testing indicates a 40-year lifespan under accelerated weather testing. Rivets are also compressed within the body rather than left exposed externally, reducing one of the most common failure points found in cheaper laminated designs.

Long Shackle Options

For applications requiring additional reach, long shackle versions are available in the 40mm and 50mm body sizes. These maintain both the weather-resistant finish and hardened steel security features of the standard models.
