3. Electronic Padlocks

Padlocks for Gates

Gates typically need strong locks that will survive in out-of-the-house climates and ensure firm protection. Use a combination of corrosion-resistant materials (e.g., brass or stainless steel) to build padlocks with weatherproof bodies. Consider using a shroud around the shackle for additional defense against bolt cutters and pick locks.

Padlocks for Bikes

Durability and portability should be two main factors when choosing your bicycle lock. Buy bike-specific ones such as u-lock or chain lock systems among others. You should also look for those that have high-security ratings like being resistant to cuttings or prying open, but still which are light enough to carry on bike rides.

Padlocks for Lockers

Convenience and reliability are very important when it comes to securing lockers at schools, companies, or gyms. Combination padlocks often fulfill these criteria as they do not require any keys. Look for combination locks that are robustly built with smooth turning dials reducing delays during opening.
