Best High Security Weatherproof Padlocks
Best High Security Weatherproof Padlocks
If you need a padlock that can withstand rain, salt air, frost, dirt and constant outdoor use, the Abus Extreme 83WP series is one of the strongest all-weather solutions available. It combines two specialist metal treatments: the Granit weatherproof coating and the nano-protect finish used in the Abus 41 series. Together, these provide long-lasting corrosion resistance in exposed environments.
Key Security Features
The Abus Extreme padlocks include hardened alloy steel shackles, anti-pick cylinders and a double ball bearing locking mechanism for increased resistance to pulling and twisting attacks. A built-in keyguard also helps prevent grit, dirt and debris entering the keyway, which is particularly useful on construction sites, farms or coastal locations.
Open and Closed Shackle Options
This padlock is available in 53mm and 63mm open shackle sizes, plus a closed shackle version in the 53mm size. The closed shackle gives extra protection by limiting access to the shackle, making it harder for bolt croppers or pry tools to be used. All versions provide strong weather resistance.
Recognised Insurance and Security Ratings
Both padlock sizes meet the BS EN 12320 standard. The smaller 53mm size carries a CEN 3 insurance rating and Sold Secure Bronze, while the larger 63mm model increases this to CEN 4 and Sold Secure Silver.
Key Retaining for Better On-Site Practice
The Extreme range is key retaining as standard. This means the key cannot be removed unless the padlock is locked. This is useful in shared environments where padlocks are sometimes left unlocked or misplaced. If required, the lock can be converted to snap-shut operation with technical guidance.
For the Toughest Coastal Environments: The Abus Submariner
If your padlock will be used beside the sea or in areas exposed to salt or ammonia, consider the Abus Submariner 83WPIB/53. This version uses stainless steel internal and external components and is designed for full marine exposure. It is used in demanding environments including North Sea wind farms, where corrosion resistance is critical.
Keying Options
The Extreme and Submariner padlocks can be supplied key differ, keyed alike or with restricted key profiles. This allows you to match multiple locks to one key, control key duplication, or manage master key access across teams.
